Unlike with regular attacks, NOTHING can stop a monster effect
When monsters go here, unless you state it, they always become Spells, and if they equip themselves to a monster, they become Equip Spells, and also are considered an Equip Card
In this way, each player (and their chosen character) will have access to more and more abilities each turn, and the creep of these powers is iterative in a way that means its entirely possible to keep track of both what you can do, and what your opponents can do
Their power comes from the extra value you get on top of playing enchantment cards, and building up a critical mass of triggers to outpace your opponent
