This was the deck I was using to get to Infinity Apr/24 before they changed Zabu, and it was working pretty nicely, as I usually wait to upload decks once I get to infinity but this one didn't have the chance, I'm saving it a bit for historical purposes (and expecting they change Zabu back, something I thinks it's likely to happen considering what they said in the patch notes).
This deck is based on Dark-Thing Lad https://snap.fan/decks/274969/ that was based on Dark-Thing https://snap.fan/decks/273464/ (both original decks I made too) that worked very nice until Darkhawk was nerfed. Darkhawk replaced with Omega Red and Rock-gifters with Howard (to take more advance of Iron Lad as a possible Tech-card and Enchantress.
Zabu made the higher cost card a 3-cost, so you could play 2-cards in last turn easily, hence the "Cheap" name. You can counter almost everything, hence the "Tech", and and at the same time create enough power using Man-Thing and Omega Red (usually together, hence "Omega-Thing") but always below the card biggest power being 10 (avoiding Shang). You also take advantage of Jeff and Captain Marvel movement to access some locations (that usually also received power from Omega Red. If your rival use some over-the-top power building you get both Shadow-King and Shang-Chi to counter.
