Turning all your artifacts into Mox Sapphire and coming into play with a massive artifact creature is great, but its activated ability gives you an outlet for all that surplus mana
So your packs may come with all kinds of colours, not a lot of land cards, and varying rarity cards
The Battle of Commander Sets In terms of Commander-oriented sets, we already had a set release once before that was Commander themed: Battle for Baldurs Gate
Equipment are a subtype of Artifacts, and have the ability Equip, which can be used at sorcery speed
and Rise of the Eldrazi, a card named after an MTG set which merges the cast abilities of each Eldrazi titan
Pack your lifelinkers, big creatures, and artifact removal
