Eldrazi have a reputation for being hard to deal with in the late game , so you'll likely be targeted from the get-go as soon as you reveal Ulamog as your commander
This combined with Ezio's ability to make an opponent with ten or less life can lead to wins much quicker.
He owns a three-card set in which the first and second Trainer cards have been graded PSA GEM-MT 10s, while the third is a PSA 8
Favorites include Dreamscape Artist, Diplomatic Escort, Jaya Ballard, Psychic Frog, Skirge Familiar to add mana, Stronghold Biologist and Machinist to counter creature/noncreature spells, but my two all-stars would be Chamber of Manipulation and Overtaker, turning your land cards into creature-stealing effects for fun and profit
Shadowspears lifelink and trample prove invaluable in converting Commander Damage wins, and in staying alive
When in doubt, lean towards consistency as the main priority in your deck building
