nightmare moon mtg card My Little Pony then exile those cards Nightmare Moon // Princess Luna

With all of these things in mind, the Prison deck I am going to start testing when Dominaria releases will look something like this: U/R Prison -- Modern | Jeff Hoogland Planeswalkers (2) 2 Tezzeret the Seeker Instants (4) 4 Whir of Invention Artifacts (33) 1 Bottled Cloister 1 Crucible of Worlds 1 Damping Sphere 1 Grafdigger's Cage 1 Pithing Needle 1 Sorcerous Spyglass 1 Sun Droplet 1 Talisman of Dominance 1 Tormod's Crypt 1 Witchbane Orb 2 Chalice of the Void 2 Expedition Map 2 Pyrite Spellbomb 2 Welding Jar 3 Engineered Explosives 4 Ensnaring Bridge 4 Mishra's Bauble 4 Mox Opal Lands (21) 1 Mountain 6 Island 1 Academy Ruins 1 Ghost Quarter 1 Inventors' Fair 1 Ipnu Rivulet 1 Tectonic Edge 2 Darksteel Citadel 3 Shivan Reef 4 Tolaria West Wrapping Up This Prison deck not only feels powerful, but has a lot of flexibility to keep me entertained while I find new lines with it

These are very scarce, and as such very desirable

The drawback is its triple-blue mana cost, meaning almost all of your lands in your deck have to tap for blue for you to cast this card reliably

It's a removal spell dedicated to lifegain decks, the same way you might consider Drag to the Roots in a dedicated delirium deck
