Approach the Necroblossom

Put a +1/+1 counter on target creature. That
creature gains vigilance and indestructible until
end of turn.
Replication - If you've cast a spell with the same
name as this one this turn, you get an emblem
with, "As long as it's your turn, creatures you
control have first strike if a creature you control
has first strike. The same is true for flying,
vigilance, double strike, and indestructible."
