The idea with this army is to keep it cheap. So I will be using as many of the Spire of Dawn models as possible. I will sprinkle in a handful of conversions to spice things up and to eliminate extra command models when possible. So here is the list of models I will need:

Highwarden

Archmage + mount and leg bits

3 sets of spireguard + extra bits from skycutters to convert command

3 sets of swordmasters

4 sets of reavers + sister of averlorn bows

2 Skycutters + oval bases

The initial cost of the Spire of Dawn set was $60. I traded the Skaven for another set. I was able to pick up the other Reavers for $7 a set +shipping, and the extra Swordmasters and Spireguard ran me roughly $40 total. I got super lucky on the mount for the archmage, so the leg bits set me back $11. In the end the only real expense was the Skycutters at $105 for the 2. So in the end, current cost was roughly $250. In all honesty, it's not the cheapest army I could have made, but under $300 for an army is still a steal. My stormcast cost a lot more than $300.
