Rate my team! Dragon Slayer + Squad

Hey, does this team look fairly solid?

Team: Nowi, Myrrh, Alm, Fallen Takumi

The main core is the first three, although Fallen Takumi is doing crazy well for me right now.

Nowi (+Def-Res) / Lightning Breath+ Def / Reposition / Bonfire / Steady Breath / Guard 3 / Fortify Res 3 / Quick Riposte 3

Myrrh (+Res-Def) / Great Flame / Swap / Bonfire / Fury 3 / Quick Riposte 2 / Hone Dragons / Iote's Shield

Alm (+Spd-Res) / Falchion (+Eff) / Reposition / Glimmer / Death Blow 3 / Windsweep 3 / Threaten Def 3 / Attack +1

Fallen Takumi / Skadi / Reposition / Moonbow / Fury 3 / Desperation 3 / Spd Smoke 3 / Speed +1

Thoughts? Right now, Nowi deals with Brave Lyn early on, while Myrrh draws in Rein and soaks his hits so I can kill him the next turn. Alm is for breaking Hectors, Grimas, Amelias, and for just general mass destruction. Fallen Takumi is really my only good archer other than NY Corrin, and I love his cleanup potential with all the doubles from Fury and Desperation. He just makes a solid unit for me, and gives the team range on offense rather than just Nowi's Distant Counter.

I think in the future, I'd ideally want to try Fallen Takumi with a Brave Bow and Brash Assault seal, to go for quadruples. I'd also want to give Myrrh either Distant Counter or Lightning Breath+, since right now, I'm using her as a mage counter and soak.

So how's the team look? I know it's not great for super high arenas as a mostly-F2P player because it'll be hard to find merges, but I have a different core already planned for that (Soleil, Nowi, Nino).
