The Endurance Bobblehead will tap to give X dorks +1 power and indestructible for the turn to save them, also at sorcery speed for three mana
One will shoot stuff, and draw you a card when you do
While neither carry a hefty price tag, both are excellent Commander cards that see tons of play in Magics most popular format
I also quite like green-blue-red, which combines the best Lander cards, efficient removal, and powerful bombs from green-blue and green-red into a coherent three-color strategy
It's also possible to place this on an opposing creature if it gives you more bounce for your buck, but then you'd lose that counter
Im estimating your chances at a colored Chocobo at 0.03% because all the others add up to 99.97% and the serialized is such a tiny percentage that it doesnt matter
