Mulligan for Sky Yaks, Octopus, Elementals or even Earthcraft
Best starting land: Forest, in front of your face
After that, the best play is to have an Earthcraft to double special land to one side (if you have octopus or elementals), if its already defined the side your opponent going, it is better to go on the other to collect faeria with the jump creatures.
If you have Sky yaks you don't even need Earthcraft at all on the start, and it will be better to make your way offensive for the opponent creatures.
You can use aurora creation with almost every creature on the deck, whales and frog tossers for removal, fugoro for combos, sky yaks for swarming, etc.
Emperor command is a very versatile card, can reduce the opponent's creature attack rapidly and still have your creature alive, beyond the healing and the structure removal it can provide, it is very useful and situational.
If you want, you can flex the swordfishes with some other card, but the taunt dash mechanic is very good on some sittuations, even because you will always have forests close to face.
