Holon's Castform (1 as a tech) can really help you even your energy needs. Plusle and Minun can help keep the pressure up by returning your :fighting: or :water: energy and drawing 2 more cards after one of your pokemon get's KO'd which will happen a lot in this type of deck. Absol EX can help control when the damage counters are on your opponents pokemon to maximize Sharpeedo's attacks. Spinda might be a decent starter in this since it has the possibility to be very offensive in the right situation in addition to being able to draw 2 extra cards a turn.
