At the beginning of each combat, each creature you control gets +1/+1 until end of turn if it has the same name as another creature you control or a creature card in your graveyard.
: Another target nontoken creature you control gains
first strike (This creature deals combat damage before creatures without first strike.) and
double team (When a creature with double team attacks, if it's not a token, conjure a duplicate of the original into your hand, and then both cards lose double team.) until end of turn. Activate only as a sorcery and only once.
