The problem is that the second one is just too strong, let alone the third one. You are paying 4 mana for a Spiral Technique, which can be even better if you have an Obelysk on board.
It’s really a bad card, which steals games, and it was totally obvious since it was announced. I think it should be nerfed or reworked completely. It’s even hard to argue against it, given how plain of a problem it is…
