Callidus AssassinCallidus Assassin is too expensive for a single target removal, even if we get something in exchange
Gettin Mama Odie, Mystical Maven out there early - which should be doable thanks to the cheap cost of the card - alongside a handful of songs, will very quickly put you into a position wherein you can play a lot more cards per turn or a much more expensive, and more powerful, card a lot earlier than your opponent
Although it's not necessarily the strongest by raw power (despite having the highest attack stat of any Duskmourn commander), Valgavoth's ability ensures that its attack and block will grow rapidly, especially when combined with the right cards
Be extra weary of anyone who doesn't take the free +1/+1 counters
This expressly does not allow you to break timing restrictions, so don't try pitching it if someone else forces you to discard on their turn
