PonderAdded -
Spark DoubleReasons: There is a lot of Top Deck Manipulation in here already and though
Ponder does not hurt it just seemed a little more beneficial to have the
Spark Double in the deck to allow for either double activation on a specific walker or the utility to have a copy of some creature you control. With that said, removing
ponder was fine because if you need to
spark double can become
Riverwise Augur which is just an ETB
Brainstorm on a stick. In short, the
Spark Double is just better versatile utility that not only fills the gap that
ponder left on removal but also adds flexibility.
