Why look for a specific creature for dragons?
Do you know how many Eye of the Storm you can get by the end of the first month if there's a lair of these creatures near your castle? Castle growth + lair presence + the creatures from the lair + portal 14+1+7+7=29 Eye of the Storm per week with a developed castle. You can gather a hundred Eye of the Storm relatively quickly - there would be enough money, but that's not a big problem with a large number of ranged units like the Eye of the Storm and Medusa, supported by Harpies and Witches. -)

Resurrection is always available if you play as a hero with resurrection and build a Mana Vortex. -))))

And who would attack a Scorpius? Neutrals? - unlikely, as long as there are ranged units and Trolls. -))))
It's a shame if an Eye of the Storm appears in the summoning portal.
