Knight of New Alara In just a Selesnya deck, Knight of New Alara can buff your multi-colored creatures by +2/+2, making simple creatures like Catti-brie of Mithral Hall and Conclave Guildmage 4/4s
Not only that, but even if your opponent is swinging in with a 10/10, you can still block it and gain 10 life, because thats how damage works in MTG
Its a very well-rounded set for EDH and what better way to expand your Commander options than choosing a Commander Legends booster
Build your deck right and every creature in your yard is coming back
Skipping your attacks to flop out an Obelisk is horrendous should they just kill it with some artifact removal, it is pretty bad if they wrath your team, it will take several turns to get back on track even with the Urd still in play
