So how do the turbo-charged ponies recharge (if they haven't destroyed their boosters)? This is how. The card's info says: BTTR-EN031: Recharge Now Continuous Spell Once per turn: You can target 1 Level 4 or lower Pony or 25th Pony-Type monster with 0 ATK or DEF; it gains 3000 ATK or DEF, based on its battle position, until the End Phase. If its ATK becomes higher than its original (printed) ATK: Destroy it during the End Phase. (Common)
