Ah Raichu, one of my faves, I was exited when his level X was released.

Raichu here is one of those cards that makes you go "OMGZ, AWZOMEZ!" then the thought comes... and it's "Aw crap"
Let's explain. When Rai is played, he can attack twice, one of which he can target the bench at the cost of 2 Electric Energy from the hand. Now, why is this not as good as it seems?
1 In the current Format there is no real way to keep the hand with a constant flow of energy.
2 Raichu is a 1 trick pony, and to my knowledge, there is no way to delevel him outside of SuperScoopUp or wait till he dies, then Premier Ball him back to the hand. The other problem there lies in he needs 3 energies to attack. This is too long to set up in the current Meta.
Raichu, you are the little mouse that could. If we could bring back energies in a faster way, you would be fantastic. But we can't. Raichu LvX.. 5/10 The possability is there, but at the current time you are a bench warmer.
