The protection the sword gives means that not only can your opponent not target the creature with spells and abilities, much like Hexproof, but also means that their creatures, planeswalkers, and other permanents cannot interact with it either
This means that in addition to all the benefits that already come with an extra turn, within that extra turn, this spell's caster has access to a massive 15/15 with flying an annihilator 6
Developed by Cryo Interactive, is the first of the Dune computer games
It even includes popular, hard-to-find cards likeJester Confit,Cosmic Cyclone,Storming Mirror Force, andDimensional Barrier
This sort of effect has been shifting into white (see: Generous Gift), so its actually a pretty unique form of green removal
Priest of the Haunted Edge is a nice blocker in the early game with four toughness and can be used as a removal spell later in the game once you control enough Snow lands to make it worthwhile
