@YourNeighborhoodGhost thanks!
It was the first Marisi deck on Deckstats so I had to come up with a tactic on my own. I own an oldschool cube with some very old cards so my thoughts went automaticly to creatures with shadow and horsemanship.
About your suggestions:
Righteous Cause might actually be pretty good with all creatures attacking every turn.
I thought of
reconnaissance myself in the beginning but turned away from for the same reason I removed
Odric, Master Tactician: Most creatures in this deck are already unblockable or have very good evasion so I believe there is No need for these specific cards.
Gustcloak Savior on the other hand could be interessting as it is a creature with evasion on its own.
