Noob arena question

[ChaosBat]

Howdy;
When I clicked on "Click to Test" my own arena deck (never had noticed that before), the deck I played had 70 cards but the deck I had entered was only 35 cards.  Are all arena decks automatically doubled?

The deck is doubled when you invest in Dexterity [The last row in upgrades.]

[ChaosBat]

And there is no option to stop this?
Are there any other deck changes made by choosing other options?
Thanks for the info!

That's the only deck change option.  If you don't want it, you'll just have to not invest in Dexterity in your next deck.

Doubling your deck size is a good thing for the most part, since it doubles the number of creatures, spells, and pillars you have. The double draw also helps a lot.

Doubling deck size would have been good if I hadn't already been taking into account the double drawing and making the decks bigger anyways.  Ended up double doubling on some decks.  Does it say that Dexterity will have this "side effect" anywhere in the Arena deck builder, and I missed it?
Again, thanks for the info.

Don't really understand what you said there, but no, it doesn't say anywhere that dexterity doubles your deck size, sort of like how the game doesn't tell you adren is passive and can't be lobo'd.

Actually in the lower right side of Arena Deck point allocation screen, it does list "Deck Size" and when you pick Dexterity it goes from 1X to 2X.  I just had never noticed it.  Mea Culpa.
