Prized Amalgam works very well in Commander, though you need to focus less on the body and more on building a synergy engine around a creature continuously dying and reanimating
This can quickly happen if you play with Recycle, Worry Beads, Anvil of Bogardan, Riptide Director, Tolarian Serpent, Cephalid Vandal, Prosperity, Ambassador Laquatus
River Bear River Bear has a reasonable enough mana cost that it can be played earlier in the game, especially in a green deck
Besmirch Besmirch is a strong tempo play, as youll get a good attack on a turn, and the creature's goaded on the next turn
It doesn't matter if youre an MTG rookie, a seasoned player, or collect and re-sell MTG cards - the Collector booster boxes offer a sure-fire way to quite literally stack decks and add heaps of new, rare cards to existing piles of MTG goodies
I create these lists prior to checking their play numbers on EDHREC
