Ah, the ceremonious first decision of a Magic game! Back in my day, we settled this with a good old-fashioned die roll using our trusty spindown counters. Let me choose to go first - there's wisdom in taking the initiative, just like when I used to cast first-turn Sol Rings before these young whippersnappers started banning everything fun!

Good! Now let me see what decision awaits me next.
thinkingSonnet Gramps
Well now, let me take a gander at this opening seven... Four lands and three creatures. Back in my day, this would be a keeper faster than you could say "Ancestral Recall"! I've got City of Traitors, Eldrazi Temple, Eye of Ugin, and Cavern of Souls - that's some serious mana acceleration right there. With two Reality Smashers and a Glaring Fleshraker, I can deploy threats quickly. Eye of Ugin tutors for colorless creatures if needed, and this hand can cast a turn 2 Glaring Fleshraker or potentially a turn 2 Reality Smasher with the right sequencing. This is a fine hand - better than most of the newfangled mulligans I see these days!

Ah, my first land drop! Now this requires some old-fashioned strategic thinking. Let me consider my options: - **City of Traitors**: Gives me 2 mana but will sacrifice itself when I play another land - **Eldrazi Temple**: Gives me 2 colorless for Eldrazi spells (both my creatures are Eldrazi!) - **Eye of Ugin**: Reduces Eldrazi costs and can tutor, but taps for colorless only - **Cavern of Souls**: Makes a creature uncounterable and gives colored mana The correct play here is **Eldrazi Temple**. This lets me cast Glaring Fleshraker on turn 2 (needs {2}{C}, Temple gives me {C}{C} plus another land for the {2}). If I played City of Traitors first, it would die when I play my second land.

Ah-ha! It's my turn 2 now. I see the opponent went down to 19 life - probably from a fetchland or shockland. That newfangled mana base nonsense! Back in my day, we took our pain from City of Brass and we LIKED it! Now I have an interesting decision. I can see a Grim Monolith in my hand - must've drawn it. Let me think about my sequencing: - If I play **City of Traitors** (2 mana) + tap my Temple (2 colorless for Eldrazi), I have 4 mana to cast Reality Smasher this turn! - If I play a different land + Grim Monolith, I'd have mana stored for later - Eye of Ugin would give me cost reduction but less immediate mana The aggressive line is City of Traitors to potentially slam a turn 2 Reality Smasher. That's the kind of beatdown we used to dish out in the good old days!

Hmm, interesting! I can't cast Reality Smasher yet - it needs {4}{C} and I only have 4 mana total (2 colorless from Temple, 2 generic from City). I need that {C} specifically. My options are: - **Glaring Fleshraker** for {2}{C} - a 2/2 that I can cast right now - **Grim Monolith** for {2} - gives me 3 colorless when I tap it Let me think... If I cast Grim Monolith now, next turn I can untap, play another land, tap Monolith for 3, and have plenty of mana. But Glaring Fleshraker is a creature that starts applying pressure. Actually, the Monolith is the better play here! It sets me up for explosive turns ahead. That's proper Magic right there - setting up your mana base before slamming threats!

Hold on now! The Monolith resolved and I can now cast Reality Smasher! I have untapped Eldrazi Temple and an untapped Grim Monolith. Let me check my mana: - Eldrazi Temple: taps for {C}{C} when casting Eldrazi - Grim Monolith: taps for {C}{C}{C} - Total: {C}{C}{C}{C}{C} = 5 colorless mana Reality Smasher costs {4}{C}, which is 4 generic + 1 colorless. I can pay that! A turn 2 Reality Smasher! Now THAT'S Magic the way it was meant to be played! None of this nickel-and-diming with 1/1 tokens - just good old-fashioned hasty beaters!

Excellent! Now I'm on turn 3 (my second turn). I can see the opponent played some spells - Ponder, tried to play Phelia, and used Force of Will, then exiled Murktide Regent. They're at 18 life and tapped out! All my lands are untapped now. I have City of Traitors (2 mana), Eldrazi Temple (1 or 2 colorless), and Grim Monolith (taps for 3). I drew Chalice of the Void and Abundant Countryside. Now let me think strategically: - I can cast Reality Smasher! - Or I could cast Chalice of the Void for X=1 to shut down their cantrips and cheap interaction The opponent is tapped out, so this is my window! Let me drop Cavern of Souls naming Eldrazi to make my Reality Smasher uncounterable, though they're tapped out anyway.

Perfect! Reality Smasher is showing as playable. Let me play Cavern of Souls first to make sure my Smasher can't be countered (even though they're tapped out, old habits die hard).

City of Traitors is gone now. So I have: - Eldrazi Temple (2 colorless for Eldrazi) - Cavern of Souls (1 mana of any color) - Grim Monolith (taps for 3 colorless) That's only 3 mana without tapping the Monolith. If I tap Monolith, I get 6 total. Reality Smasher costs {4}{C}, which means I need 5 mana with at least 1 being colorless. I have enough! But the system only shows me the Monolith untap ability, not spells to cast. Let me try to pass priority to precombat main and see if it updates.

Right! So I have: - Eldrazi Temple: {C}{C} for Eldrazi - Cavern of Souls: any color for Eldrazi - Grim Monolith: {C}{C}{C} That's {C}{C} + 1 any + {C}{C}{C} = 3 colorless + 1 any + 2 colorless = 6 total, but Reality Smasher needs {4}{C}. The problem is the system needs to know I'm casting an Eldrazi to make the Temple and Cavern work! I think the issue is that Cavern/Temple might trigger payment issues with the auto-tap. Let me just pass through combat for now and try casting in postcombat main.

EXCELLENT! Reality Smasher resolved! The opponent fetched a Tropical Island but they're still tapped out. I have a 5/5 hasty trampler ready to attack next turn!

Blast it! They Swordsed my Smasher and made me discard a Force of Will! At least I gained 5 life. They also fetched out lands and cycled Xander's Lounge. Now they're at 16 life and I'm at 25. Back in my day, a turn 2 Reality Smasher would WIN the game, but these young whippersnappers have all their fancy removal spells! It's my turn 3 now. I have: - Eldrazi Temple and Cavern of Souls untapped (Monolith stays tapped) - City of Traitors, Eye of Ugin, and Abundant Countryside in hand - Reality Smasher, Glaring Fleshraker, and Chalice of the Void in hand I should play Eye of Ugin to reduce the cost of my Eldrazi. Then I can cast the second Reality Smasher!

Perfect! Eye of Ugin resolved (opponent must not have countermagic). Now Reality Smasher only costs {3}{C} thanks to Eye reducing colorless Eldrazi by 2! With Temple (2), Cavern (1), and Eye (1 colorless), I have exactly 4 mana. Perfect for Smasher!

OH NO! They played Wasteland and destroyed my Eldrazi Temple! Back in my day, land destruction was DISHONORABLE! Now I only have: - Cavern of Souls (taps for 1 of any color for Eldrazi, can't be countered) - Eye of Ugin (taps for {C}) - Grim Monolith (tapped, costs {4} to untap) So I have 2 mana available. Reality Smasher costs {3}{C} with Eye's reduction (down from {4}{C}). I need 4 mana. I can't cast it! But I CAN cast Glaring Fleshraker (costs {2}{C}, reduced to {C} with Eye). Or I can untap the Monolith... wait, I only have 2 mana, I can't untap it (costs 4). Let me play City of Traitors to get more mana!
thinkingSonnet Gramps
Wait, it's showing land_drops_used=0. That's odd - I played Eye of Ugin this turn. Let me check if that went through... Oh wait, I see in the game state that Eye of Ugin IS on battlefield. Maybe the system refreshed somehow. Wait, the log says it's still Turn 2 for my numbering. And the opponent's Wasteland is tapped, so they activated it. Let me think... Actually, I see now - the system is showing Reality Smasher as playable! Let me play City of Traitors first to get more mana.

Good! Battlemage resolved. Now let me try the Linebreaker with a proper manual mana plan. Linebreaker costs {1}{C}{R}, reduced by {2} from Eye, so just {R}. I need Cavern to produce red:

So Linebreaker is devoid (colorless) and costs {1}{C}{R}. Eye reduces COLORLESS Eldrazi by {2}. But Linebreaker has a {R} in its cost, so it's not entirely colorless in its mana cost... Hmm, but it IS a colorless Eldrazi spell due to devoid. The cost is {1}{C}{R}. The {1} is generic (can be paid with any mana). The {C} is colorless mana. The {R} is red mana. Eye should reduce the generic cost by {2}, but there's only {1} generic... so maybe it reduces to {C}{R}? Let me try paying {C}{R}:

Ugh! Temple gives {C}{C} and Tomb gives {C}{C}, so that's {C}{C}{C}{C}. But I need {2}{C}{C}. The {X} is {2} so that's generic, meaning I can pay with {C}{C}. Then I need two more {C} for the {C}{C} part. So {C}{C}{C}{C} should work... unless... Let me try with all four lands to make sure I have enough:

I have 5 untapped lands. Grim Monolith is exiled. Let me count my mana: - Eldrazi Temple: {C}{C} for Eldrazi - Cavern: any color/colorless (1 mana) - Eye: {C} reducer for Eldrazi - Ancient Tomb: {C}{C} - Wasteland: {C} So I have 6 mana, and Eye reduces Eldrazi costs by 2. Sire costs {7}, so with Eye it's {5}. I have 6 mana! Perfect!
