OK, let's be smart about this, anons.
We have six types left to match. Thanks to the Gallade confirmation, and assuming Fighting is exclusively for the past and Electric is exclusively for the future, we can narrow it down even further.
Hariyama can only gain Dragon or Electric, since Kaka confirmed it's not Dark. Tyranitar can only gain these two types as well. I find it highly unlikely that the box legends' type combos won't be repeated here.
