This deck is nuts, currently very strong on the ladder. I didn't expect it to work this well.
The basic game plan is to go Saskia Commander round 1 along with movement engine maybe a dragon if needed. Then bleed round 2 with the Dragons and other cards, while also saving up for round 3. After that go for a short round 3 with Aglais and remaining dragons. Even if you miss Saskia round 1, this deck still holds up extremely well. There are many other ways to play this deck.
You should swap Epidemic for the Vial to play alongside Aglaïs, although the leader alone is enough in most cases.
