Do Exert as Replacement, even if its an Optional Cost

[Hanmac]

Exert done as new Replacement Effect

• [ ] AI needs logic when not to Exert on Attack
• [ ] AI logic needs to be extended for Pump
• [x] and Inter Trigger Effect
• [x] The Label "Exert Attacker" needs to be removed from the languages, i couldn't do it somehow

Looks good to me mechanics-wise, but the AI needs to be properly hooked up, yes. Sadly, someone would need to help with that at the moment, I'm still sort of torn between several real life issues at the moment... :/ But the core mechanics change looks good to me! :+1:

@tool4ever Exert has two types of Trigger connected to it:

• You may exert CARDNAME as it attacks. When you do, ...
• You may exert CARDNAME as it attacks. Whenever you exert a creature, ...

the first one is directly connected to the cost (and in case of a static a bit tricky) the second one is indirectly connected to the exert

and of course the AI part needs to think of both of them, and interconnected. (the first one does trigger the second one, and the second one also triggers multiple of seconds)
