lord of the rings mtg chase cards Sauron, Tales of Middle-earth Commander 0004 FOIL, NM! MTG: The Most Valuable Cards

They made a powerful combo deck that was difficult to interact with, causing Wizards of the Coast to perform a suite of bans that took almost all of the combo decks out of the format

Standard is the least certain of the bunch, mostly because cards like Magma Spray and Abrade offer the ability to remove every one-mana creature along with some two- and three-mana creatures as well, but when you consider that the next-best options in white are cards like Gideon's Reproach and Slash of Talons (discounting enchantment-based removal like Seal Away, which is probably already in your main deck), the flexibility of killing one-drops and random sideboard hate might be enough for Isolate to sneak into sideboards in small numbers

Its a fun playstyle that can be challenging to pull off but rewarding when all goes as planned
