Márton Stromgald
Oracle Text
Whenever Márton Stromgald attacks, other attacking creatures get +1/+1 until end of turn for each attacking creature other than Márton Stromgald.
Whenever Márton Stromgald blocks, other blocking creatures get +1/+1 until end of turn for each blocking creature other than Márton Stromgald.
Also, dont forget that he can be used defensively as well. His buff triggers on blocking as well so in a pinch you can play him defensively to stop a large overrun army as well.
