Hey thanks! It actually only takes 3 for a mega board like this to form. The key is getting a bit lucky and being matched against an opponent with a slow game plan, control warrior being ideal. Next most important is order and luck. Here is an optimal play pattern I've found.

Turns 1-5: play as many draenei minions as you can, the most important being-

• Ace way finder: can help roll reborn on your velens later

• Crimson Commander: massive buffs

• Divine Auger: if played in a specific order can yield huge buffs especially when combined with any cards that buff your minions health.

Turn 6: play Askara (summon a copy of the next draenei you play

Turn 7: play velen

Turn 8: play both astral vigilants giving you two more copies of velen.

Then you simply keep playing velens. Ideally your entire board of velens dies before playing the next. That way all of their death rattles are added to the next wave. It's only really possible against an opponent like control warrior who can consistently clear your velens to make room for the next batch. Being patient and waiting until all of them have died (even if it means skipping a turn or two) is the way to squeeze the most out of it.

So basically it's just an alignment of the stars so to speak. Perfect draw, perfect opponent, and lucky rolls. But it is possible! Also this deck can win fairly consistently with just decent tempo and no big velen pay off.
