Ok, this is going towards the loony bin a bit, please bare with me...I think I've about got this Gargoyle thing sorted out (we'll see). Anyway, here goes:
Gargoyle is in play, no arrival fatigue, its ready, you have plenty of gold and it has Entangling Vines attached (of course!).
You pay 1 gold, and I have it gaining a 'this card can attack and patrol the rest of the turn, no matter what' pseudo-ability, along with some +attack +flying and losing indestructible.
Can't Attack or Patrol (two instances of this, but its not cumulative, so just one instance matters)
Can Attack and Patrol No Matter What -> pseudo-ability
Note: This 'pseudo-ability' is only generated by a Gargoyle card; no other card in the game can give or create this effect. I am tracking it as being independent of the card, as it is not something gained/gets, etc. Its just something it can do. This can overrides can't. The only way in the whole game to lose this 'can attack' pseudo-ability is via Polymorph. Otherwise it just 'hangs out' as something the game 'knows' the card has. I am treating the word "Gargoyle" to mean "this exact card".
You Manufactured Truth the Gargoyle into a Young Treant (lets assume I picked Y.Treant 'randomly').
Gargoyle who is now a Young Treant
Can't Attack or Patrol (one instance of this, from Entangling Vines)
Can Attack and Patrol No Matter What -> pseudo-ability (Does this 'carry over'?)
Arrives: Draw a card. (Does nothing, but is text on the card nonetheless)
Can't Attack (Y. Treant ability)
It can attack and patrol this turn? Thoughts?
