Well, if you can MT a unit to a mirror then use quince to copy to that mirror, you can do a lot of crazy.
truth discipline balance vs disease past law
Max quince mind controls skeleton javelineer (javelin rune)
Sparring partner (javelin, +1)
MT javelin to become a mirror
Copy opponent shimmer ray using mid quince
Mind controlled skeleton javelineer is now a mirror that became a shimmer ray.
Discard a card to get a time rune. (Javeline,+1,time)
End of turn. MT effect end so the card is back to being skeleton javelineer and doesnt get trashed to quince midband.
Opponent plays insurance agent insuring your skeleton
MT javelineer to sparring partner
Play dragon and put a feather on the sparring skeleton partner
MT into mirror
Copy opponent juggernaut
Suicide it once to get crumble ruin
End of turn MT wears off and back to just javelineer
(javeline , +1 , time , insurance , feather ,crumbling )
As a bonus oppponent activates plague lab and gives you 1 more rune of each kind
