For me it is not recommended since you only can use one skill at one time. If you use surprise present skill but ug as monster, no point since once you attack that 2000 defend monster, you lost 1400 lp already because no holy guard effect to protect you.
Yeah, the potential of jbm to ruin opponent chance to turn the table is magnificent. How can they do that when they can't perform any summon except that token? I never thought this skill is really reliable in farming
