LINEUP: Chose Shieldbearer as my tank as because of it's ability taunt, have high health and 4 shield too. Now, because of the taunt ability of Shieldbearer, I can use other monsters of low health too as I will not be worried about enemy having opportunity ability. Plus having peakrider as my summoner I can choose monsters with low health too. was just worried that what if the enemy chose magic?
Peakrider also works well when you got weak magic or lost magic as the ruleset.
