Ondu Spiritdancer - With this one out first, you get two copies of Yojimbo Champions from Beyond This enchantment gives you tokens, card draw, and a giant team-wide buff
Aristocrat decks that make and sacrifice numerous creature tokens, for example, are perfect for Mirkwood Bats
[EDITORS NOTE heres the other one, for the curious] Taking after the original Millstone and Grindstone, this artifact offers the perfect blend of simple enabler and combo-riffic payoff
A combo of Cultivate and Explosive Vegetation is awesome, and the more colors in your deck or format (like Five Color), the better this is
With a combat bonus for swinging at your opponents, players are likely to take the opportunity to get some hits in
This one requires two mana and only prevents combat damage, but it justifies its existence with a ferocious effect
