I'm back with yet another deck building game question. Assuming a deckbuilder was to be played using the traditional style of "discard your hand and draw 5 new cards", but also included direct player vs player combat, how would you expect the combat system to work? Most deckbuilders don't have costs or restrictions on the number of cards you can play aside from Dominion, but I'm guessing you'd have to create some kind of cost or restriction Allow me to provide an example. Lets choose a traditional fantasy scenario of a wizard fighting a wizard by summoning creatures and attacking with them. Without costs or restrictions, I can simply empty my hand onto the table and summon five creatures every single turn. This doesn't sound very successful.
Thoughts?
