Relentless Warlord

Other creatures you control have haste and must
attack each turn if able.
At the end of combat on your turn, if a creature attacked and didnt deal combat damage to a
player or planeswalker, sacrifice it. When you do,
you may put a creature card from your hand onto
the battlefield.
