When this card is activated: You can banish 1 card from your hand; Special Summon 1 Level 4 or lower "Chemicritter" monster from your Deck in Defense Position. You can only activate 1 "Activation Energy" per turn. Once per turn, if a Gemini Monster is Special Summoned to your side of the field: You can make it become an Effect Monster, and gain its effects.
Activation energy in Chemistry is the amount of energy required to begin a reaction and keep it going, with this card doing both of these things for a measly 1 banish from the hand. Synergized but generic, depending on what you want to do; my favorite kind of support. Might be a tad too easy to trigger though, so...
