Ideally played with a strong condition such as good Artifact, emblem, or many copies of Veigar / Ornn. Sacrifice Lifebloom plant to Blackthorn early. Late game you can sacrifice Leblanc 3 for big stats -> move her items to another spellweaver. After you cash out first Ornn artifact, move items to Alistar.

Stage 2: Only play around this opener with early upgrades so Veigar can snowball and gain stacks. Prioritize Veigar items.

Stage 3: If you are close to Veigar and Ornn 3 (7+ copies), consider rolling until you hit 3*. If far (3-4 copies), slow roll above 50g for 3*.

Stage 4: Once you finish Ornn 3 and Veigar 3, you can slowroll on 6 for Leblanc + Alistar 3, if you are too far push levels..
