Razorfield Ripper

Whenever Razorfield Ripper or equipped creature attacks, you get {E} (an energy counter), then it gets +X/+X until end of turn, where X is the amount of {E} you have.
Reconfigure—Pay {2} or {E}{E}{E}. (Pay {2} or {E}{E}{E}: Attach to target creature you control; or unattach from a creature. Reconfigure only as a sorcery. While attached, this isn't a creature.)

每当锐草原贯裂犀或佩带此武具的生物攻击时，你得到{E}，然后它得+X/+X直到回合结束，X为你具有的{E}数量。
重配～支付{2}或{E}{E}{E}。
