Jaya Ballard requires mana and a discard, but you can activate any ability immediately without worrying about counters
Furthermore, it costs three mana and a creature just to get a 3/3 out of it
Loxodon Warhammer (SLD foil $10) Adding three power is the magic number for both of them, and while a classic, you especially want trample on Tifa

The flexibility is the main reason to play this
