Infinite game breaking loop with umbral collar zealot and 2x creature cards with return card to battlefield when you commit a crime.

The first loop occurred on the openants turn, it lasted several minutes where they just kept sacrificing the same two creatures repeatedly, while they racked up counters on the rest using long feng secrateriat and ouroboroid.

Immediately after this I cast to exile umbral collar zealot, only to have them repeat this loop, again. This time their turn lasted so long that they had to utilize a timeout even though they were actively performing this spam loop for the 5 or so minutes. The player did this until they reached the card they needed to win (via the scry ability on the zealot card)

There seems to be several ways this cards ability can be abused and break the game. Outside of a card that blocks all activated abilities, there is no way to stop this infinite loop and even then you would have to hope to pull/play that ability before the 3x cards needed for the infinite loop.

PS. Am I the only one who feels like the RNG for card draws has gotten significantly worse after the most recent update? (12.11.25)
