Max Walker VIII, Time Cop

First Strike
{w/u}{w/u}{ut}: Max Walker Phases Out
(While it phased out, its treated as though
it doesn’t exist. It phases in before its controller
untaps during their next untap step.)
Whenever a card comes into play from exile,
put a +1/+1 on Max Walker and tap target
creature. It doesn't untap until their next
end step
