Can Tryndamere's ability win the game at 6 points if you only conquer one battlefield (not both)?

Question

Accepted Answer

No — if you are one point away from the Victory Score and Tryndamere’s ability causes you to Score by Conquering only one Battlefield this turn, you will not immediately win. Instead, per the Scoring rules for Conquer near the Victory Score, you draw a card unless you have Scored every Battlefield this turn. You can only win immediately if the Score that would give you the Winning Point is a Hold, or if your Conquer is the final Score of every Battlefield this turn.

If Tryndamere's ability causes you to Conquer a Battlefield while your current Points are one away from the Victory Score, you will not Gain the Winning Point from that Conquer unless you have Scored every Battlefield this turn. If you have not Scored every Battlefield this turn, you draw a card instead of gaining the point. If the Score was a Hold (not a Conquer), you would Gain the Winning Point.

Start with the player one point away from Victory (one less than the Victory Score). Tryndamere's ability causes a Score by Conquer on a single Battlefield (you gain Control of a Battlefield you had not yet Scored this turn) [464.1]. Because you were one point away from the Victory Score when trying to Gain a Point through that Score, apply the special Winning Point rules for Scores at/near the Victory Score [466.1.b]. Since the Score was a Conquer and you have not Scored every Battlefield this turn, you do not Gain the Winning Point — instead you draw a card [466.1.b.2]. You will only Gain the Winning Point from this Conquer if, at the moment you Score, you have already Scored every Battlefield this turn (so the Conquer is the last required Score) [466.1.b.2]. Alternatively, a Hold that gives the Winning Point would succeed immediately [466.1.b.1].

If Tryndamere's ability grants a Point by some other means that is not a Score (not a Conquer or Hold), that point is not subject to the Winning Point restrictions per 466.1.a.1. In that case the point could let you reach the Victory Score immediately. If an effect effectively treats a Conquer as 'as if' it occurred (see some battlefield activate/conquer interactions), you still must check the conditions in 466.1.b.2 to determine if the Conquer grants the Winning Point. See relevant clarifications where abilities ‘treat’ a conquer as occurring [FAQ:unleashed#23]. If some effect changes the Victory Score during resolution (for example, replacing a Battlefield that modifies Victory Score), the timing for whether you are 'one point from the Victory Score' may shift; see the discussion in [FAQ:unleashed#12]. If you have already Scored every Battlefield this turn (for instance you previously Held or Conquered the other Battlefield this turn), then this Conquer can grant the Winning Point and let you win immediately [466.1.b.2].

The Core Rules treat gaining the final Winning Point differently depending on whether the Score was a Hold or a Conquer. If you are one point away from the Victory Score and you Score through a Hold, you Gain the Winning Point and can win immediately [466.1.b.1]. If you Score through a Conquer, you only Gain the Winning Point if you have Scored every Battlefield this turn — otherwise you draw a card instead of gaining the point [466.1.b.2]. A Conquer is defined as gaining Control of a Battlefield you have not yet Scored this turn [464.1]. Also note you can only Score once per Battlefield per turn [465].

Putting that together: if Tryndamere's ability makes you Conquer only one Battlefield while you are one point away from the Victory Score, you do not win immediately. Because that Score is a Conquer and you have not Scored every Battlefield this turn, the rule replaces gaining the Winning Point with drawing a card [466.1.b.2]. The only ways that Conquer would let you win immediately are if you had already Scored every Battlefield earlier this turn (making this Conquer the final Score needed) or if the point is gained by a method that is not a Conquer or Hold (those are not subject to the Winning Point restrictions per 466.1.a.1).
