It's working as sergeant berry intended to, BUT i've tried this deck and pulling out this combo is extremely difficult:
1) you should save 2 sergeant and 1 berry to do this on 10th turn. which means, 3 dead cards on your hand and you have to survive until 10th turn
2) many zombie decks are agressive, you will be dead before turn 5 or 6 because 3 dead cards
3) 4/3 with 4 cost is easily killed. survive on turn 5 and pull out combo on turn 6 is really RARE case.
4) mostly win because of others plants like Grape or Blueberry, not infinite combo
shield is working properly. you can play super card ONLY when all damage iteration has been count, so infinite loop damage is certain death.
