yugioh battleguard cards Cadet up monster on the field to face Battleguard Rage Card Profile :

Thats not even accounting for how large the card selection might get with future updates

Even if the monster survived the lightning bomb, it is dangerous to leave the monster on the field because its attack power has dropped by 2000 because it is so weakened

Boil and the like are certainly in the latter group and I think we can all agree no one wants to see those in the cube

Other takes on this strategy have centered on Brain in a Jar, which has the disadvantage that it can be slow to get going late, but its advantage, in addition to not being an enchantment, is that it has an interesting combination with Days Undoing that allows you to cast Days Undoing on your opponents turn, skipping the end the turn clause, which means that the Days Undoing ends up in your graveyard

This is great for the archetype since it allows you to send Maiden With Eyes of Blue to the graveyard during the Link Summon
