It won't be everyone's cup of tea, but I do quite enjoy Epic Spell Wars Of The Battle Wizards: Duel at Mt. Skullzfyre.
Its a simple game, but good fun if you're with a group of people who don't take their gaming too seriously and like to joke around with things. The game is 2-6 players, each person is a wizard and you are all fighting to become the last wizard standing. At the base of Mt. Skullzfyre.
Each player has a hand of 8 cards and 20 health, all together you look through your hand and create a spell made of 1-3 cards. Each spell can have a source, a quality and a delivery. Smaller spells are faster to cast but less powerful, so generally you will want to use all 3 cards. Once everyone has picked, you all reveal at the same time. The delivery of the spell has an initiative which is how long it takes to cast that spell, so the fastest spell goes first, and so on. Resolving the spells is simple, just do what it says on each card. Also, you have to say the name of the spell as you cast it, in a deep wizardy tone!
And you make spells like:
On the delivery where you need to roll a die (And some source and qualities as well) the number of dice you roll is determined by the number of components which match the same element as that card (Such as arcane, death, primal etc).
The game is hectic fun, you can't control who you target because it is down to the cards. And while you can have a rough idea who the strongest foe is when you pick the cards to play, if you have a low initiative and lots of other spells resolve before you, its likely that there will be a different strongest foe when you do cast.
As I said, its not for people looking for a serious game, its more a silly filler game, there isn't tons of strategy, the only question is usually if you want to cut a card from your spell for the initiative, but even then it isn't a huge choice, but with 8 cards you can make some interesting spells, and there are some that let you chain off ridiculous combos too.
