How Shaman of Forgotten Ways works in 2HG
Shaman of Forgotten Ways tries to set each player's life total to a specific number, but how does that work when you have two players and only only life total? You pick one player and ignore the other when resolving the effect!
Targeting troubles with Dromoka’s Command.
Dromoka's Command has a lot of the word "target" on it, and it can be tricky to know all the legal ways to cast it. Read and absorb some knowledge here!
Thunderbreak Regent only triggers for Dragon permanents.
Thunderbreak Regent's ability is powerful, but don't get carried away. It only works while the Regent is on the battlefield, and it only triggers when an opponent targets one of your dragon permanents (on the battlefield). It doesn't work for dragon spells on the stack or dragon cards in the graveyard.
Manifest and Delve (no, you can’t!)
Delve only functions while you're casting a spell, and turning a creature face-up via manifest isn't casting anything. So you can't benefit from delve when turning a manifested Gurmag Angler face up, for example.
Getting value with Humble Defector.
Humble Defector's ability doesn't give away control until it resolves, and the card draw is not dependent on giving away the creature... so if you find a way to untap him and reactivate the ability, or kill it before you draw, you can get extra value out of it!
Soulfire Grand Master and Rebound (you choose).
Rebound and Soulfire Grand Master's ability are both replacement effects trying to replace the same event (spell going to graveyard as it resolves), so you get to choose which one to apply.
Exploit week: Responding by killing the creature with exploit.
Killing an exploit creature before exploit resolves ensures that the secondary trigger won't be around to trigger when the sacrifice would be made.
Monastery Siege, et. al. – An explanation of draw step triggers.
Monastery Siege and other draw step triggers can only go on the stack and resolve after you've drawn your card for the turn, making them considerably better than the other way around!
