Allora per le liste non ti so dire molto, però ti posso aiutare con le regole.
Per quanto riguarda protector
CITAZIONE
Protector (600.4): Only one applicable character with protector can protect each proposed defender each attack. A character that can protect a proposed defender can do so whether or not it can be attacked by the character attacking that proposed defender.
600.4 Each of any applicable characters with protector that isn’t a proposed defender that can protect may choose to protect a proposed defender. In each case, the proposed defender stops being a proposed defender, and that protector becomes a proposed defender. This is the only time characters can protect. Then, all proposed defenders become defenders and “are attacked.”
Praticamente protector ti permette di sostituire un difesore di un attacco con il personaggio con protector, se anche lui non è difensore dello stesso attacco, vedi per esempio attacchi AOE. Nota che i due alleati devono essere adiacenti.
Per i buff e di conseguenza i debuff:
CITAZIONE
Buff (301): Buff core abilities can target only allies. Playing a buff card’s core ability attaches a “buff” to a target
character. Such a buff is allied with the party of the character that played it as it’s attached and has all the text of
that buff card, but is otherwise independent from that card and that character. As part of attaching a buff to a
character, all other buffs attached to that character with the same name as that buff are removed. As part of
destroying a buffed character, all buffs attached to it are removed. A buff can be attached to a totem, but is
removed immediately after the ability that attached it has finished resolving.
Quindi in poche parole un personaggio può avere su di se un qualsiasi numero di buff ( o debuff), ma solo uno con lo stesso nome e velgono tolti quando il personaggio "buffato" viene distrutto, essendo indipendenti dall'eroe che li ha lanciati.
