Uba Mask/Possessed Portal

[Buttons]

Possessed Portal

If a player would draw a card, that player skips that draw instead.
At the end of each turn, each player sacrifices a permanent unless he or she discards a card.

Uba Mask

If a player would draw a card, that player removes that card from the game face up instead.
Each player may play cards he or she removed from the game with Uba Mask this turn.

I'm going to draw a card - can I put Posessed Portal's triggered ability on the stack first, then Uba Mask's, so that I can still use the card?

I'm almost positive this is right, but I'm just checking with you guys.

That said, if I stacked the Uba Mask first for my opponent, than the Possessed Portal,

The triggered ability of the possessed portal would resolve, but the Uba Mask's ability wouldn't be neutered, would it?  He'd still get to remove it from the game, right, or would the Portal's ability cease the Uba Mask's ability to exist?

These are not triggers.  These are replacement effects.

When you draw, you get to chose which one to apply to your draw first, then the other applies if it is still applicable.  So, you could apply Uba Mask first and remove the card instead of drawing.  Then Possessed Portal doesn't do anything as there is no longer a draw to modify.

However, you can't chose how to apply replacement effects for your opponent's draws. They also will get to chose how the replacement effects are applied to their draw as well.

having uba mask in play circumvents the you-cant-draw effect of posessed portal. Ive had this happen in a match against cerebral assassin. even though he had squee and p-portal, I was able to outrace the double-sacking effect w ubazaar and win.
