Just noticed that for the utility of the card and to say that it plays into a lot of other Spellhai / Backhai mechanics, Juxtaposition should absolutely NOT cost 0 mana.
It’s effectively a free removal / free backstab if you have any sort of minion on the board.
For it’s utility, it should be comparable to other spells like Daemonic Lure or even minions like Repulsor Beast and cost 2 mana.
Any thoughts? Is 1 mana a better cost for it? Am I just being daft? Chip in.
