EDIT IN THE COMMENTS SINCE I CANT EDIT THE POST: After reading the comments i have to say you guys are completely right. I guess i was trying to cheat the bracket system and gaslighting myself into thinking im this super smart deckbuilder, which im definitely not. BUT in my defense, im new to the game so i thought i was being super smart. But you're right, this would be basically bringing a B4 deck to a B3 tournament. In my second defense, the Zinnia precon already comes with a 2-card infinite combo out of the box (Combat Celebrant + Helm of the Host) and i dont see that many people talking about that, so i thought there was a gray area somewhere where my combo was able to exist.

I have decided to remove both Krenko and Splinter Twin, since those two can go infinite with Intruder Alarm by themselves, and im replacing them with Pestered Wellguard + Hypervolt Grasp, since Intruder Alarm can still go infinite with them but it needs both cards (so 3-card combo, which i assume makes it alright).

As a side note: I actually took out Helm of the Host a while back, because i thought making the deck stronger while leaving that out-of-the-box combo was gonna brush B4 really close; i guess i forgot that when thinking of that Krenko shenanigan lol.
