Gregor, New Beginnings

Double Strike
Gregor, New Beginnings gains +1/+1 for each Equipment card equipped to it.
At the beginning of your upkeep, you may put a 'customized' counter on target equipment. If a customized weapon would increase Gregor's
power or toughness, it instead increases by twice
that amount. Remove all 'customized' counters
at the beginning of the next end step.
