A quick note about "Sylvan Charity", the way it is coded, it has you select both cards at the same time, instead of the "Sylvan" card first, and then the other card second.
This means you can select a non-"Sylvan" card first, which is relevant, because after both cards are selected, there is no additional option to choose the order.
When Percy releases the next update, I imagine it will be coded in a way that allows you to choose the order on the top of the deck (via pop-up window).
