Manahive

Equivalent cards (green, similar effect: sacrifice for color fixing):
1. Druid of the Cowl (ramp, not a sac but mana fixing)
2. Leyline Prowler (some mana fixing, has deathtouch/lifelink)
3. Elves of Deep Shadow (taps for colored mana with minor downside)
4. Sakura-Tribe Elder (sacrifices for land, commonly used for ramp/fixing)

All are green and help with mana/colors in some way. None are a perfect match, but these are close.
