A 3-mana land-fetcher is right on curve for a lot of effects
Despite the effect of transforming Battle being a triggered ability , its controller exiles the permanent and then casts it without paying the mana cost , opening up space to interact with Battle on the stack with Make Disappear, or other counterspells, or even to bounce them on the stack, with Venser, Shaper Savant and the like
Tyrranax Rex alleviates that issue with toxic 4, making this the perfect creature for decks that use poison counters as a win condition
In BO1, you can have a very explosive draw with Leyline of Resonance in your hand, and a fast aggro start that ends the game as fast as turns 2 or 3
all great, but none as fun as Living Death
Prerelease for Wilds Unknown starts Friday, May 8th at local game stores
