You Don't Have To Be Psychic To Know This is A Great Card

Apparently, it's filled with fungus.

The Cavernous Hall (The Underdark chase, 8/25) is an excellent realm to have in a mainly- or all-psionicist deck. When attacked, you can choose to defend it with a champion from your hand or pool, or you can let it defend itself. The realm champion then duplicates the level and power of one of the psionicists in your pool. This can be an amazing ability, depending on who you have out. The card-drawing ability of Highmaster Illithios. The huge level of Bansmareton. The champion-destroying power of Lyr of the Mists. Or imitate Talcon and choose to lose, dragging the winning champion along with you to the discard pile.

Play The Cavernous Hall later in the game if you can, possibly as a replacement for a razed first realm. You want to hold off on playing it until you have a wide assortment of psionicist champs sitting in your pool, so that you can take a long look before deciding which one to copy. Early in the game, your choices will be limited and your opponent will have an easier time attacking. Since there is only one attack per turn in TAV, each sortie is super important. Use The Cavernous Hall to make your enemies feel like crawling into a hole in the ground!

Extra! Check out some of the gameplay posted on the Spellfire.com website. I'm not big on playing CCGs on an app (I prefer physical cards), but this looks like fun. Plus, they are using the TAV rules! I can't wait for the Spellfire relaunch.

Next time: Show some restraint!
