Every creature becomes an Indrik Stomphowler
Traditionally, there have been two primary schools of thought when it comes to building a sideboard in Modern: You can play narrow cards that are extremely powerful, or cards that are more broadly useful
While thats it for mechanics, I wanted to talk about 2 more card types
Sealed : While Tarkir: Dragonstorm doesn't have a ton of counterspells in the set itself, there are still a few tucked away
For two generic mana and one white mana, Boromir, Warden of the Tower does a lot on its own, and is an auto-inclusion if you play a stax deck with white in it
I won't be able to participate in the market for cards like these, but I sure hope I can at least sit back and watch.
