Spindle Harvesters

Question : If a player controls a Rare "Spindle Harvesters" and a Rare "The Spindle, Muna Bastion", can they first boost the Spindle harvester, then benefit from that extra boost to draw a card?

Answer : Yes!
At Noon, all effects that say "At Noon" are triggered, then are resolved in the order of their controller's choice.
When a player resolves Spindle Harvesters, they check everything on the right side of the " — ". If Spindle Harvesters has two boosts at that moment, its controller draws a card).
