(Assuming that your cards have equal %s as well... let's say 20%)

When you are attacking someone whose defense team you do not know: all boosters

When you are attacking someone whose defense team you know to be weaker than your attack team and/or is a mixed-type: all boosters

When you are attacking someone whose defense team you know to be stronger and also pure-type: all reducers

When you are just defending in general or you've got someone with a grudge coming after you: all boosters

If and only if you seem to always get attacked by a certain type (for example, divina whales love you, but no anima or phantom teams have ever challenged you for a long time): all reducers
