If the Loser declares an upset do ties now go to the offense as opposed to the defense?
Does the Morph card copy the opponent's card before any other effects, or does it, for example, copy the value of the Tripler's card after it's been altered by his power (as his power states that it changes the value of the card)?
1. It's easier to think of it like this: 1) The values are equal, so it's a tie. 2) The defender wins on ties. 3) The defender wins, and therefore loses when Upset is in effect.
2. The Morph becomes a copy of the card's printed face value for all intents and purposes the moment it is exposed/revealed. It is a static effect that does not duplicate any effects that other powers/Flares may have on the card it is copying. To use your example, if I play a Morph and my opponent (the Tripler) plays an Attack 10, the morph immediately turns into an Attack 10. Then Tripler's power makes his card worth 30. If the shoe is on the other foot, and YOU are the Tripler, and you play a Morph, you apply your power to whatever the Morph becomes.
In a way, the Morph does not have a definite face value until the original face value of the opponent's card is determined, but upon that happening, no other game effect should pre-empt it. This effect is atomic; there is no way to interrupt it, happens all at once, and then does not carry over into any other game mechanic. It's tight like that.
Some additional examples of playing the Morph:
vs Chosen: Takes the form of Chosen's originally played card, not what he may eventually swap/combine it with.
as Chosen: Morph says "takes form of opponent's encounter card when revealed." This is one for the next FAQ - does it copy the opponent's card when it is turned up during the Divine Intervention draw (which could result in it being added to Chosen's played Attack card), or if/when it actually becomes Chosen's selected encounter card?
Pacifist: If Pacifist or his opponent plays a Negotiate, the Morph becomes a Negotiate as well, and Pacifist can't use his power.
as Reserve: "when revealed" implies that it only applies itself as an encounter card; you cannot play a Morph as a Reinforcement if your opponent's encounter card is an Attack 6 or less.
as Calculator: if Equalize is declared and opponent plays an Attack card, then Calculator's effect shouldn't occur because there is no "higher" card.
as Fodder: since both cards are identical after Morph copies, there's no gap of Attack values that Fodder can play in.
as Hate: Plague defines Morph as a distinct card type from Attack and Negotiate, so playing Morph as your "hate card" is a guaranteed 3-ship penalty for all other players.
Mirror: Morph copies the opponent's card, and both cards have their digits reversed, effectively doing nothing to change the result by default.
Citadel: Morph only becomes an Attack Card when it's used against an Attack card in an encounter, so you can't use it as a citadel.
Gambler: Although a very tricksy bluff to sell, you can say, "My card is the Morph". Although the FAQ should answer this question: Say I'm defending, my opponent and I have equal ship counts, and he has played an Attack 10 (a common card with multiple copies in the deck, so not hard for me, as Gambler, to sell that my card could also be an Attack 10, tying the totals and therefore winning). If I say, "My card is an Attack 10", the attacker challenges me, and I reveal my Morph, does it become an Attack 10 before or after the point at which Gambler is determined to have lied or not?
I welcome debate on these unofficial interpretations.
