Aetherworks Marvel (and similar cards) have confusing interface

[Clipper70]

Aetherworks marvel only looks at the top 4 cards of your library when activated when it should look at the top six

[xenohedron]

Could not reproduce as stated. It does look at the top six, but it only displays spells, so you don't see the lands. Probably still worth fixing.

Same logic is used in other cards:

• Svella, Ice Shaper
• Velomachus Lorehold
• Kiora, Sovereign of the Deep

The problem is that CardUtil.castSpellWithAttributesForFree() filters directly to castable cards and only shows a choice window for the castable cards if there are two or more. This is fine if the cards come from zones that the player can already see, but not sufficient if the cards come from the library and haven't yet been shown.

I think the preferred functionality, in this case of "look at the top X cards of your library", would be for the choice window to show all the cards, but with only the castable cards selectable. (That is, there should not have to be separate windows for looking at the cards and choosing a card to cast.) Probably the best way to accomplish this is to make a new common effect class that these four cards can use.
