I just try to block super aggressively. That's why I like eternal, grow, attack dice. Play the dice, then outlast the baddies. In Pokémon, this would be the "spam toxic and potion" strategy :)
I don't really know that well Pokémon but I get what you are talking about, tough I have to ask, If you are always playing the eternal block die, then way not make it hollow & grow and just always play it?
