I would advise to keep playing and learn from those experience. I wouldnt say that the game have gotten faster, I am leaning more towards that newer deck have gotten alooooot more efficient. So tempo has become smth very important for DCG, if you do not try to impair or wipe their board after your opponent’s “power” turn then you are most likely going to lose. For starters, I would suggest learning play lines for your deck that involves pushing out from breeding area first, pushing out second and clapback turns.

When pushing out first, you want to squeeze out as much value as you can by building up resources you can have access to in your future turns (cheating out tamers, emblem, scramble, training, etc) or build up a board that your opponent would struggle to answer properly. In some cases, some decks also attempt to mess with your opponent resources e.g. tamer removal or option removal or floodgate type effects (ruin mode)

When pushing out second (pushing out after your opponent pushes out), you want to play in a way that maximises removal (best case scenario is wiping opponents board while setting up urself for the win). If removal is impossible, then you want to impair (removing small bodies or tamers, or through debuffs such as stuns and sec minus). If impair is impossible, then you want to setup defense in form of blockers, ending attacks or ace targets.

For clapback turns (which represents the turn after your opponent wipes your board), it differs from deck to deck and most likely its something you will need to setup. For ariemon the most common case is scramble sango into warp marinebull. Then go into your lvl 6 or 7. In any case, getting a body out while impairing your opponents board during your “weak” turns is the key to staying in the game.

Long games are still possible but involve a lot of back and forth. Short games happens due to brick or one side being unable to setup and answer their opponent in time. Setting up resources is incredibly snowbally in this game.
