Is there a limit to the upgrades each turn?
I have seen 11 copies of the same card go-to my opponent!
Do you really need that many 10/10 rhinos!
If I recall correctly, Togwaggle’s scheme has a cap of 45 (or whatever the deck size limit is). Similarly, Rafaam’s scheme has a limit of 7 ( because you can’t fit 8+ imps on board simultaneously). Hagatha’s, Lazul’s, and Boom’s schemes do not have a limit beyond the game’s own turn limit.
The limit is how many you can have by the rules.
Decks can contain a max of 65 cards.
Board only 7 minions
Armor is around 1,250 billion(gain more than the cap and it returns to 0).
And if a spell damage passes the max armor 1,250 billion as well. I not know exactly happens because i never did but by sure it will not do more damage than that because the game can’t calculate above the armor cap.
Deck cap is 60 for the record.
Also note that Drakkari Enchanter causes Schemes to trigger twice.
