valgavoth mtg commander deck Pain, Power & Punishment put a +1/+1 counter on Valgavoth Elite Commander Demon Deck -

So using a card from your hand as a resource is clearly not a new mechanic

To the Crystal Tower (Cryptic Command) Rating: 7/10 In a world where spending 4 mana on noncreature spells is a supported archetype, I cant think of many better cards to spend my 4 mana on than Cryptic Command

With it not effecting the board and the ability to scry for various amounts make it easy to tag on to things in a balanced manner and not make them too powerful

Can it detect infinite combos in my deck

Right now, this seems to be more true for Lorcana than it is for other trading card games, which often have top tier decks stuffed with cards that are hard to get hold of
