Let me challenge you with the following rules:
- deck size: minimum 40 cards
- upgrades, shards and nymphs all allowed, so any card (full meta)
- each element can only be used in maximum Four games
- each element combination can only be used in One game (e.g. mono-fire only once, time-dark duo only once etc.)
- if an element is used in a deck, it has to contain minimum 5 non-PPM cards of that element (no minimal splash to pretend its a new element combo)
