Wizards of the Coast has been reprinting and remaking a lot of the older cards as different colors. What caught my eye was the new 'Ball Lightning' which adds a huge power bonus to red/green now if you combine both of these 6/1s.
Ball Lightning: 6/1 RRR
Trample
Ball Lightning may attack on the turn during which it is summoned. Ball Lightning is buried at the end of the turn during which it is summoned.
(The text above basically means Haste)
Groundbreaker: 6/1 GGG
Trample, Haste
At the end of turn, sacrifice Groundbreaker.
In my opinion, this is CRAZYYY AWESOME.
