This could've been a decent card, but the friendly-fire on the second attack killed it...
The first attack is OK for 20 plus damage counters x10, and it also heals self for 20, so it can help it staying in and stalling in early game (only against basics).
But for the second attack, 80 plus 10 to each benched, can be quite annoying at times, to both you and your opponent. Either way, the cost is too high, and the friendly-fire isn't really worth it. It does do very well when it's the only Pkmn you have in play, though, but you risk losing the game by having no active.
100 HP is decent for a stage 1, but its 4 RC sets it right back so that when it's in, it pretty much stays in until KO'ed. G+30/L-20 is OK since there are much less Grass types now, but there aren't that many Lightning types either.
5/10 - Could have been decent, but they killed it...
