You cannot move a card that has already changed its battle position
This way, instead of getting counters on an artifact that you have to tap for mana, instead, for each Pentad Prism you control with a counter on it, you get one mana every time you cast a noncreature spell for each Flux Channeler you control
Once per turn, you can remove 3 Kaiju Counter on the field to prevent your opponent from activating cards or effect this turn, and allow this monster to attack monsters 3 times that turn
Umbra armor has no effect if the enchanted creature is put into a graveyard for any other reason, such as if it's sacrificed, if the "legend rule" applies to it, or if its toughness is 0 or less
Instead of running X amount of card draw spells, for example, you can cut out the weakest ones and just tutor up the best ones when needed
