I can see having cards in your deck that tap potential attackers, like Icy Manipulator and Opposition, so if an opponent doesnt draw a card from your commanders ability, you know you can keep your tap-down effects ready for potential attackers from their side of the battlefield
This add-on full of Magics most desired enchantments will show up in Draft, Set and Collector boosters, much like we saw with March of the Machines Multiverse Legends and The Brothers Wars Retro-frame artifacts
The card itself more than makes up for it, and annoyingly enough has reach, which will be problematic for many an EDH deck
Ideally you're putting the counter on an Attraction that has 3 lights lit up so you have a 50/50 of getting the exiled spell each turn
Cumulative Upkeep Pay 2 Life, for which you couldnt attack but had a safe barrier between you and damage as it said, Prevent all damage that would be dealt to you. Of course, youd still have to deal with Glacial Chasm itself hitting you every turn
