Each starter deck comes with a deck of 60 cards, two of which are foil cards, 11 damage counters, 1 paper playmat, 1 paper Lore tracker token, game rules, and a booster pack with 12 cards
If you're counting on Winged Sliver or Muscle Sliver or any other boost to carry you through combat, then a removal spell on the key ability can destroy your entire team, and even with Hibernation Sliver available such a blow is often crippling
This card could comfortably serve as the commander of a go-wide, token creature deck, or a lifegain deck
If the trigger was changed to target creature gets the counter, and you draw a card', it's countered
If Amulet Bloom falls off a bit, Primeval Titan could easily find itself in the $6-$8 range before long
Perhaps its because Im more competitive at Magic and feel the need to optimize, but I think the mechanic itself encourages this fairly painful behavior
