Calderan cradle market

Reliable fetch Calderan Cradle from Market and cast in round 4 with one of 10 Market Fetch cards Rust Grafter, Howling Peak Smuggler, Ixtun Merchant, Jennev Merchant, Primal Etchings or Fire Etchings.

The deck has 23 spells, of which some lead to multi-casts Bore, Unstable Form, Re-read and Frostburn. The site Garden of Omens and the attachment Sacred Tableau, as well as 8 spell generating units such as Kazuo, Melee Virtuoso, Portent Reader, Wind Channeler, Siege Train or Jotun Hurler, and another 6 power cards with spells Rune of Flame, Rune of Trickery to accelerate spell-casting. In most games I get two 5/5 Dragon out.

The remaining creatures either support or benefit from spell-casting Kennelmaster, Fevered Scout, Icicle Marksman, Midias, Leyline Dragon or Pyre Elemental. Occasionally, Hexdriver can hit big once.

Early aggro is contained having nine 1-2 cost units including Borderlands Waykeeper or Frostpact Sprite and four 1-2 cost damage spells. With mostly 1-3 cost cards, only eleven 4-6 cost cards, none higher (apart from Market), the deck develops fairly reliable.

Some of the cards are still a bit random like Geminon, the Double Helix and allow further optimization.
Suggestions are welcome.
