Esper Sentinel is a 1/1 Human Soldier for one that allows you to draw a card whenever your opponent casts their first non-creature spell in a turn
Battlecon attempts to simulate a 2D fighter video game with just some cards, character standees, and a small board and nails it
It doesn't copy whether that creature was tapped or untapped, whether it had any counters on it or Auras or Equipment attached to it, or any non-copy effects that had changed its power, toughness, types, color, or so on
Still, the exclusive nature of the BWR makes these cards highly desirable and likely to be one of the top collector items from modern sets for quite some time
they effectively only cost 1 mana since they recoup half the cost instantly
If your deck uses the promo Skarmory from the Cresselia ex Drop Event, swap it for the two-diamond version from Space-Time Smackdown
