Avenger of Zendikar's starting 0/1 Plant tokens (or 1/2 if you choose to play your land for the turn after casting it) are dangerously frail
If you activate its ability by removing a +1/+1 counter from it, it now has 2 toughness and is destroyed as a state-based action
Then for the symbols of mana it's the common: wubrg for white, blue, black, red, green
That said, Rampaging Ferocidon is now just another three-drop in a sea of good red three-drops, and you could just as easily end up wanting Goblin Rabblemaster, Goblin Chainwhirler, or no three-drops at all depending on how you build your red decks
Alternatively, players can make one-off payments for the premium currency Pok Gold, which can be used instead of Pack Hourglasses to unlock packs or be exchanged for rare cosmetic items
loose, bubbled, generic, or re-glued wrap is a warning
