Will The Heavens' Blessing force you to pay 2 gold to draw cards off of A Game of Dice?
Based on the wording of The Heavens' Blessing "Open: Until the game ends, a player must pay 2 Gold to draw a card from effects of his own Strategies during an Action Phase." I would guess the answer is no, since you aren't actually drawing in the action phase, even though A Game of Dice is played during the action phase. On the other hand, the effect of A Game of Dice is technically applied during the action phase, even though it has no effect until the end phase. Would A Game of Dice cost 2 gold if The Heavens' Blessing is in effect?
The Heavens' Blessing: Open: Until the game ends, a player must pay 2 Gold to draw a card from effects of his own Strategies during an Action Phase.
A Game of Dice: Limited: Draw two additional cards during your next End Phase.
