Good point. At least Punishing Fire gets it. The last build I tested had 3x Trophy main so cards like that weren't an issue. Cut those for cute stuff. Might need to trim some cute stuff to be a functional deck.
Didn't realize Wurm was for that, thought it was for combo or burn. I had noticed your other anti-flyer tech doesn't answer Marit Lage, so I opted for Edicts as the Murktide/Archon answers because they also deal with Marit Lage. Run Afoul is probably best at hitting the right problems for the least mana.
Do you find Wurm fast enough? Depths can make T2 20/20. Reanimator makes Archon fast. SneakShow can make T2 threat. I feel like we need a fast answer.
Brazen Borrower,
Gilded Drake,
Phantasmal Image,
Stingscourger or just
Swords to Plowshares/
Solitude are all viable answers. If white is your 3rd color instead of red then it's easy.
