­Celestial Crusader + Evard's Spiked Tentacles

­Crusade on a stick, with split-second and lock down a creature, or slowly kill it and deal damage to its controller. It's like Wanderlust.

I think we've had creatures that flash in -1/-1 counters. Probably not split-second ones though.

I think it's better to be more "No attacky!" though. Yeah, let's do that.

I think I'll deliberately leave the "I attack your planeswalkers" hole. This guy only protects you.

Nifty. Fog for a turn plus kill a smallish attacker.

Doesn't really take advantage of split second for anything. Like I can't see any responses opponents might want to make to this that they can't just do after this arrives. Celestial Crusader could be used to defend a 1/1 against a ping or a 4/2 against a Shock, etc, but this doesn't do that.

Ok, they can kill it (but you still get the fog) - it makes it uncounterable, is just about all.

Not everything is a puzzle :)

You don't still get the fog if they kill it after it resolves but before you declare blockers (which they definitely have the opportunity to do).

"Not everything is a puzzle" - but every part of a card should have a reason for being there. Molten Disaster, Sulfur Elemental, Take Possession all had obvious benefits to having split second.
