The problem is, when the opponent sees a 400 or less, they'll automatically assume that you are planing a duck and win-esq card, ora G-power switch card. Other than that, good strategy.
i know, but i forgot to mention if your whatever bakugan is a 720 g and he doesn't land there then you just go ahead and go on his card and fight and win,though it is risky. though thanks for the comment Lux.
