If Noosegraf Mob is no longer on the battlefield or no longer has +1/+1 counters on it as its triggered ability resolves, you cant remove a counter from it and wont get a Zombie token
Almost every set has alternate frames with unique styles and art for the marquee cards, and the bonus sheets also get multiple art variations

The ratios here is okay: we have lower than average mana sources but the deck has an aggressive curve, and there are 2 notable ramp bombs Manaweft Sliver and Gemhide Sliver
