Coat of Allegiance

When Coat of Allegiance’s activated ability resolves, in addition to gaining a resource point, a continuous effect is generated where, for the remainder of the turn, the only cards you may play are cards that are Draconic. This only affects cards that are played, not cards that are activated. I.e. you may still activate cards that do not have the Draconic talent.

If an effect is active that restricts cards being played to only Draconic cards (e.g. Oath of Loyalty, Coat of Allegiance), continuous effects that cause cards to gain the Draconic supertype (e.g. Fealty, Brand with Cinderclaw) allow you to play a card without the printed Draconic supertype (i.e. a generic attack action card) while under that restriction. That card would gain the Draconic supertype as part of playing the card from those types of continuous effects.

If an effect is active that results in cards you own to lose their talent supertypes (i.e. Erase Face) you would not be able to play any cards with the printed Draconic supertype while under Coat of Allegiance’s restriction.

If an effect is active that results in cards you own to lose their talent supertypes (i.e. Erase Face) and an effect is active that restricts cards being played to only Draconic cards (e.g. Oath of Loyalty, Coat of Allegiance), continuous effects that cause cards to gain the Draconic supertype (e.g. Fealty, Brand with Cinderclaw) would allow you to play any card in this scenario. This is because even though a card would lose their supertypes, it would gain the Draconic supertype as part of playing the card from those types of continuous effect (and you can’t lose a gained property).
