The card game Ascension is s pretty solid game. It has wonderful synergy between cards and a mechanic that is quick paced and has a good amount of strategic deck building. The gameplay drawback is its ridiculous randomness, particularly when you purchase expansions. At times these expansion sets are reminiscent of playing Chutes and Ladders or Candy Land since you can randomly gain free cards by the dozen. That said, if you are selective with which expansions you buy the game is better balanced. Check board game geek to see which ones are ideal.
The real issue with this isnt the gameplay. Its the slowdown. If the AI gets certain cards, too many cards in hand, or too many cards interacting with each other on the table it grinds to a halt. Ive sat and stared for a minute or two waiting for the computer to slog through placing a few cards on the table. In a game where turns last an average of 10 seconds this is truly unforgivable, especially on an iPhone 6. A game as streamlined as Ascension shouldnt consist of 20 minutes staring at nothing and 3 minutes playing. Give this one a pass until playdek does something about the terrible slowdown.
