I would play it at 2WU, Being bigger than abrupt decay and able to cast it earlier and protect it (assuming its in a durdle.dec)
That being said if it had that CMC and was a 4/4 I wouldnt play it as now its in WL helix and mortars range. 5/5 for 4CMC would make it mythic.
(and command doesn't read "Another target")
Also spellskite reads "Change a target"
