Re: The Correct Use of High-Voltage Current
I think game flow, board and your current (no pun intended) hand dictate when you use a Currant. But remember you do draw a card from it as well. I play it on turn 1 regularly because the real meat and potatoes of my Berry deck are Strawberrian and Sargeant Strongberry and I use to for Strawberrian evolution.
To be honest I never find it particularly useful to consider Currant something worth keeping on the board but merely a distraction. Yes it gets insanely strong when you tag a board full of zombies with a sour grapes or you get a good Strongberry loop but at 1 health it will always be a juice box.
