Actual Battlez Arena, Jade League. Free to Play (F2P) strategy using only free plants that relies on Laser Bean and Primal Potato Mine for damage and crowd clearing, and Pokra for her slowing effect. Plant Food (PF) are all used on Tile Turnip'd LB and PPM, and PF use timing is key. Almost always defeats all 3 Jade League Cardio Zombies; the 3rd one has gotten away twice, both due to lack of PF. Scores can vary a bit, but average well over 4.5 million.
Remember to shovel up Spikerocks to make room for PPM to land. Note: in the rare cases when the 3rd Cardio Zombie gets away, it's due to lack of PF, and I believe this happens because sometimes PF released by tombstones in the bottom row will stay below the screen and thus can't be retrieved. Sometimes they will float back up for about a second, so you have to be vigilant and fast.
