Ludwig Light of the Church

Vigilance, First Strike. Whenever Ludwig attacks, exile the top card of your library face down. If it’s an Equipment, you may cast it this turn and repeat this effect once, plus once more per repetition.

{t}: Discard your hand. Add all cards exiled by Ludwig to your hand, then lose life equal to the number drawn. For every 3, create a 2/2 Spirit Knight tokken with Vigilance and "Whenever it attacks, exile the top card of your library face down."

Ludwig gets +1/+1 per card exiled by its effects.
