Voice of VictoryVoice of Victory is by far the best mobilize card: It's cheap to cast, fairly resilient, it gives you the counterspell-pass for your turns, and it also prepares you coffee (it doesn't, but it may as well do)
These Commander Decks are ready to play right out of the box and each deck introduces 10 never-before-seen Commander cards
While many do run Scapeshift, they are not Scapeshift combo decks
Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for convoke
Each Play Booster includes 14 Magic cards, with 1 to 4 rares or better, 3 to 6 uncommons, 6 to 9 commons, and one land card
Better yet, you can actually read every bit of text and stats on the card
