Alright, so I had GB Explore made ready to play, and I decided to play a PPTQ at Amazing Discoveries - Gilbert. Got there and decided to panic-throw this together.
R1: UW Tokens
Game 1 is fast, Snek sticks and makes stuff big. He has a board, but a top decked Herald wins.
Game 2 is a little longer. He has no early action, but sticks a Monument, 2 Procession and explodes.
Game 3 was dragged out. He was slow on land, but I didn't have too many threats. He gets to 5 and casts Fumigate. Heroic Intervention ftw.
2-1
R2: UB Control
Game 1 drags on, but Azcanta flips and he has too many 1 for 1s.
Game 2 was fast. I mull once, but hit duress and plays. Stick a threat thanks to Duress and he scoops on 4.
Game 3 was almost as fast. I scooped this time.
1-2
R3: UB Control
Game 1, Gearhulk sticks.
Game 2, he mulls to 5(4?). I get him down to 2 life, but he flashes in Gearhulk, and I forget my Scavenger Grounds in play.
Quick 0-2.
Left here. The board was more green than the blue I intended because I forgot my blue cards at home and didn't want to buy extras. I'll partially attribute my losses to control to that.
As for the cards I did play, Metallic Mimic was underwhelming, which is unfortunate since I loved it in Human decks. Herald was hot garbage. A 4-drop do nothing is underwhelming when it relies on you having a board when it comes down.
As for changes I'd make, I'll be swapping out Heralds for Hostage Taker. Card is too good. The Mimics may become counter spells, or draw cards.
The following changes have been made:
-3 Herald of Secret Streams
+3 Hostage Taker
-4 Metallic Mimic
+4 River Sneak
-4 Attune with Aether
+4 Opt
-4 Aether Hub
+2 Drowned Catacomb
+1 Scavenger Grounds
+1 Forest
-2 Island
+2 Swamp
If anyone has any suggestions, I'd appreciate them. Thanks for reading!
