Can't Untap effects needs to be rewritten

[Hanmac]

Can't Untap effects needs to be rewritten, some could be Statics, some could be SpellAbilityEffects.

Different Cases:

• Keyword CARDNAME doesn't untap during your untap step. → Static Ability using "CantUntap(Phase)", don't need for Continuous ?
  • Also use it for effects like "doesn't untap during its controller's untap step for as long as EFFECTSOURCE remains on the battlefield."
  • Some Effects target a Player: Creatures target player controls don't untap during that player's next untap step.
  • Some Effects target a Player and be affected cards: Tap all creatures target player controls. Those creatures don't untap during that player's next untap step. the Tricky part is "that player"
  • Drawback of Spells and Activated Effects that say: doesn't untap during your next untap step need to remember You as affected player.
  • For Effects, we also need to be careful who is owning it, or if the Effect should continue for other players
• Hidden Keyword This card doesn't untap during your next untap step. → CantUntapTurnEffect using N for counting down on the Card. This is only when it means Controller

Better issue for #984

See also:

• You may choose not to untap CARDNAME during your untap step. should be a static?
• Also untaps during each <Player> untap step which should be affected by some of the stuff above
  • CARDNAME untaps during each other player's untap step
  • CARDNAME untaps during each opponent's untap step.
