Haha what a great incentive to figure out how to place your monsters in the worst positions. I will give it a try.

Ok, I will go with the Green-Team.

Summoner: Lyanna Natura (she has the highest Mana Cost)

Tank: Swamp Thing (Yes, he is a Range Attacker and can't attack at the first position, and he is very slow and a support monster - if he fails, you will loose instantly all your debuffs on the other Team...yeah what a great move!!!)

Second Position: Rexxie (Because you already know that Swamp Thing will fail as a tank, and here you go with Rexxie as a Backup. She also costs so much Mana - 8 points, that it is ridicules to have her on the team anyways. Maybe she also gets crushed thru magic blasts and sneak attacks, but Rexxie can't heal itself, so there is a great chance of loosing her... yeah that rocks!!!)

Third position: Flesh Golem (Another Tank highly costly Monsters in the back...what a great idea!!! He probably could be able to survive some attacks and would fail after Rexxie. So he might be able to be in first position and actually attack the Opponent. Lets hope, that he gets taken out by sneak and snipe attacks lol :-)

We have spent 19 Mana Points of 20 which is worse...eh good ;-)
Here you have it, my super team for loosing as many fights as possible!!!

Give it a try and don't have fun playing Steemmonsters!!!
