So, if a player summoned Exiled Force and went to use the effect, the NTP couldn't activate Mask of Restrict and stop Exiled's effect from resolving? I'm not sure that can happen.
Just look at the way a chain resolves. We know that costs are always paid first before an effect is placed on the chain. So when the turn player tributes Exiled Force, and the opponent chains Mask of Restrict, what happens? Resolve the chain backwards.
Link 2: Mask of Restrict resolves first and no tributes can be offered.
Link 1: Exiled Force now resolves and destroys one monster because the tribute occurred BEFORE Mask of Restrict became active.
This is the same principle behind the Good Goblin Housekeeping/ Emergency Provisions combo. Emergency Provision's cost is to send Spell and Trap Cards to the Graveyard. Good Goblin Housekeeping lets you draw a card for each Good Goblin Housekeeping in your Graveyard + 1 extra. So you activate all you GGH's first, then chain Emergency Provisions. Since it's a cost, can send all your face-up resolving Gogh's immediately to the Graveyard immediately, before the GGHs can resolve. Then when they do resolve, all the GGH's are in the Grave and the player maximized the number of cards he could draw per each GGH. So if he sent all three t the Grave with EPs cost, he's he'll be able to draw 3 cards +1 for EACH Good Goblin Housekeeping he sent to the Graveyard. Which would result in him drawing 12 cards. Kinda give you an idea of why it's limited to two since it came out.
Exiled vs Mask is the same principle, except the order of this chain is a little different. The cost was paid BEFORE Mask of Restrict was active. So by the time Mask of restrict becomes active, Exiled has already been tributed and is in the Graveyard, and Mask of Restrict doesn't do anything to an effect already on the chain. It's prevents tributes, (future tense) not tributes that have already happened (past tense).
Mask of Restrict is a
prevention effect. Not a
negation effect. "Prevention" stops an event from taking place to begin with, but cannot undo an event that already successfully took place. "Negation" undoes an event that already happened, rewinding the game state to before the event took place.
