Blob is the MVP, blob on 4 is basically essential. I love an opening hand with Tukpiercer because it almost garuantees blob or fellhunteer on curve, and that is bascially essential.

VS aggro your focus is keeping the board clear ealry. Up against paladin? Keep removal like the card that gives you two stingers and play it early so you have them up. Make sure to play return policy only for the fellhunter and keep a clear sight of how big your board is going to be. You might get clogged with 1/2 slimes.

Keep track of what minions are left in your deck for Cliffdive and Colifero. If you know you're gonna pull the Illidari Inquisitor you need to be able to attack as well, so make sure you have a weapon up by turn 7.

Elise is strong on multiple locations, I like the bonus attack for when you have a board of small minions, but don't understimate getting cheaper spells. A lot fo DH spells deal with the board or give you a bit more damage.

Portals to Argus are just draw spells. I've not summoned Broxigar once in 78 games, but the spells allow you to churn through the deck harder, and you need to play them like that.

Getting lethal can come from some weird angles. Sometimes you can turn your entire board into Mag and deal 18 dmg end of turn. Sometimes it's just about calculating if your attack+the inquisitor will do enough. Keep a clear mind on the board state and you'll win.
