MANAHIVE

Equivalent cards to Blossom-Clad Werewolf (green, Werewolf, ramp ability, nightbound) are:

• Krallenhorde Howler — Creature, Werewolf, nightbound, reduces spell costs (not ramp, but similar nightbound and Werewolf theme).
• Arlinn, the Pack's Hope (Transforms into nightbound Werewolf and can produce mana with a +1 ability).
• Tovolar's Huntmaster — Werewolf with nightbound, though not ramp.

All of these are green, are Werewolves, and have nightbound. Blossom-Clad Werewolf is the only one with its exact ramp ability. Green Werewolves with direct mana abilities and nightbound are very rare.
