This card is way too OP and easy to combo with rustler|leaf dragon and Jade Dragon. I have been playing around with RoL for a mutation deck I have been testing and find it easy to get over 50
by turn 6. Under no circumstance should life have a card this powerful to combo with leaf dragon. ROL, Hope, leaf dragon, mitosis and this card. just constantly pump out RoL then grant them the boost from this. if you have 5 RoL out, that's an extra 10
a turn with a leaf dragon out. Not to mention splashing
and fractaling RoL. No damage taken from physical sources because of RoL, and doing massive amounts of damage each turn because of Swell Up. And that's on top of any Jade Dragons somebody has on the field. Too OP in concept, IMO
