Omega Flowey, Nightmare

When Omega Flowey enters, put 6 soul counters on him
As long as Omega Flowey has a soul counter he has protection from everything
On your endstep, flip a coin if it's heads, remove a soul counter and create a 6/6 spirit token (it can be targeted as if it was a player or a plainswalker)
as long as you control Omega Flowey you can't proliferate or double tokens
