Yo know, I actually really want to get working on this but since the update is so close by, I could wait. Almost everything is being changed about the monsters.
Their base stats, their move pools, their abilities, and whatever.
Honestly, these tiers and clauses need to be used.
honestly, people need to actually use them themselves in tourneys they host, or we just set up a tourney review committee that has to approve the user's tourney before it goes live. get this stuff organized.
I use these in my tourneys.
<_< We need more.
Inactive Clause - If Opponent is Inactive to battle for 2-3 days they Are disqualified.
