In terms of versatility and value for money, gaming doesnt have many deals that are better than a traditional 52-card deck

If an Adventure spell leaves the stack in any way other than resolving (most likely by being countered), that card won't be exiled and the spell's controller won't be able to cast it as a permanent later

(4/17/2020) If you reveal a companion outside the game, for as long as it remains there, you may pay any time you could cast a sorcery (that is, you have priority during your main phase and the stack is empty)

As mentioned earlier, the best way is by casting your spells at instant speed, putting your creatures onto the battlefield without casting them, and stopping your opponents from casting multiple spells each turn
