Tron vs Yawgmoth 2-0

Game 1

From the Hedge Maze I initially think I'm playing against neobrand and so I want to ramp fast into casting Thought-Knot Seer. This is why I grab Ugin's Labyrinth. If I knew it was ritual, I would take the second Talisman of Resilience.

Opponent has turn 2 ritual and a Force of Negation exiling a Shardless Agent. This means, their opening hand must have had:

• Shardless Agent
• Force of Negation
• Birthing Ritual
• Harbinger of the Seas

Here I make a mistake and don't sac the Expedition Map in response, but even if I did, it wouldn't change my turn 3. I get a Forest but never really come online because I can't get {4} for Karn, and the ritual aggro beats down.

I don't think game 1 was winnable, even if I'd played better.

Game 2

I side in Disruptor Flute and out Relic of Progenitus and 2 Thought-Knot Seer.

Key mistake is not going to six to find Disruptor Flute. Should have done that. I get to discard a Harbinger of the Seas and, even though the opponent has a second one, they don't really find the mana to cast it until a lot later.

The second harbinger is causing me to keep mana open for Kozilek's Command, as I keep expecting them to find a third land, but they never do. It's not like I have anything else to cast, though, as I keep drawing lands.

I come close to lethal, but opponent is able to bring out enough blockers that, even if I managed to remove Collector Ouphe earlier and then cast Devourer of Destiny, I would never get through for the final hit.

I definitely make mistakes, like not using Dismember to save my Thought-Knot Seer, but it seems like the opponent had enough creatures that there was never a real opening.

I don't see any line that would have won game 2, other than mulligan to a better hand.

Recap

The lesson here seems to be to mulligan to find sideboard cards? But even then, neither game felt winnable.
