Re: [DMM] Pero Pero Saimin
You can setup vs potential traps. Get a team of 5 maxed out SRs of one type and always get an assist card that loses to your chosen type. So there are 3 outcomes in every duel:
-Both cards are same type, best wins(any opponent lower than rank 5 will probably have a worse card than the maxed)
-Your card has the advantage, you beat theirs(unless they beat yours using their assist)
-Their card has the advantage, you pull out the 3rd type and beat theirs)
So when an enemy team is of the type you can beat with yours, you have at least 3 of 5 cards where you have the advantage without the assist. If they assist one of theirs and beat yours, you need to do the same, and vs traps that's only achieved using a type you beat, not the same or the one you lose to since their trap card will be the same type as your assist.
It probably is confusing but trust me, I never lose to traps except to top ranked opponents that can duel out my cards with theirs.
tl;dr: 5 maxed SRs of one type,assist card only of the type you beat, never lose to lower than top rank.
