Frank, The Legion

Thrilling Tremors — Whenever Frank deals
combat damage to a player, creatures that player controls can't block until the beginning of your
next upkeep.
Feral Frenzy — {1}{b}, {t}: Target creature gets a
Deep Wounds counter. That creature's
controller sacrifices it at the beginning of their
end step unless they exert it. Activate only as a
sorcery.
