Midvinter

While Midvinter is on the field, all White, Green,
and White/Green cards have their summoning
costs reduced by {2}
While the controlling player has a Faction
Emblem on the field, Midvinter gains the
additional effect: Any Being card that is sent to
the controlling player's Netherworld creates a
Spirit Token with their name, half of their attack/defense values (rounding down), and their abilities.
