Or in Purphoros, Bronze-Blooded, a 5cmc commander full of expensive creatures, a 3cmc ramp card that taps for 2+ mana like Worn Powerstone is ideal because it lets you cast your commander two(!) turns early and start sneaking out your haymakers
The sticker removal process requires patience as to not nick the edges or corner of the card Even the most careful of removal of an adhesive sticker will leave a small amount of residue on the card, which could attract dust, dirt and other small particles

For example, if you rolled 1, 4, and 4, you'd create two Clown Robots
