저도 초보지만 몇가지 적어보면
소환후유증을 격고 있으면 탭되거나 언탭되는 능력을 쓸 수 없습니다.

탭되어 있다고 하더라도 희생 될 수 있습니다.

룰북에 있는 걸 옴겨보자면...
Summoning Sickness Rule
Informal term for a player’s inability to attack with a creature or to activate its abilities that include the tap symbol or the untap symbol unless the creature has been under that player’s control since the beginning of that player’s most recent turn. See rule 302.6. See also Haste.
302.6. A creature’s activated ability with the tap symbol or the untap symbol in its activation cost can’t be activated unless the creature has been under its controller’s control continuously since his or her most recent turn began. A creature can’t attack unless it has been under its controller’s control continuously since his or her most recent turn began. This rule is informally called the “summoning sickness” rule.

이건 희생에 관한 것입니다.

701.13. Sacrifice
701.13a To sacrifice a permanent, its controller moves it from the battlefield directly to its owner’s graveyard. A player can’t sacrifice something that isn’t a permanent, or something that’s a permanent he or she doesn’t control. Sacrificing a permanent doesn’t destroy it, so regeneration or other effects that replace destruction can’t affect this action.

그럼 소환후유증을 앓고있는 생물에겐 부여마법이나 마법장비도 붙여줄수 없는 건가요?

크로우바이츠//소환후유증은 오직 공격과 탭마크가 비용으로 들어가는 활성화 능력만 못하는 겁니다.다른건 전혀 상관 없습니다.
당연히 이큅이나 부여마법을 붙일 수 있습니다.

답변감사합니다 ^^
