Deckbuilding Mechanics in a Tactical RTS Deckbuilder Game
Deckbuilding – FAQ
What does deckbuilding mean?
Deckbuilding means that you assemble your own selection of cards. In Frontline Protocol, you create decks, and you can use 3 of them simultaneously in a match. You combine units, buildings, towers, and action cards - tailored to your playstyle.
How many cards are in a deck?
A deck consists of 20 cards. Since you play with three decks at the same time, you have access to up to 60 cards per match - allowing for immense tactical depth.
How does deck strength affect deckbuilding?
A key element of deckbuilding is deck strength. You gain it through game progression, and it allows you to include more rare cards in your deck. So you have to make tactical decisions about which rare cards are the most valuable.
Can I adjust my decks at any time?
Outside of a match, you can always edit your decks. You can choose which three decks to take into the next match each time anew. Your choice should depend on the map, your co-op team, and the difficulty.
Deck Power & Leveling
Use Strong Cards Wisely
Every card has a rarity - the rarer, the more powerful. However, stronger cards require a so-called deck strength. This doesn't increase automatically, but is unlocked through progression in the game, such as certain level-ups. This creates a central element in the deckbuilding system: You have to weigh up how many uncommon, rare, or epic cards you want to use – and when it makes sense to redesign your deck.
Common cards cost no deck power and are a valuable foundation. Uncommon cost 2 points, Rare 5, and Epic 10. As you gain experience, meta progression lets you expand your options - but smart deck planning remains key.
Diversity & Card Synergies
Over 300 Cards and free Deck Choice
Whether you build a deck made entirely of towers, action cards, structures, or tanks - it’s up to you. The Deck Designer does not give you any fixed restrictions on the card types - only possibilities. The deckbuilding system allows for creative combinations and strategic specializations, especially effective in co-op play.
Cards can synergize with map resources, complement each other, or amplify effects through clever order. Units can cover each other, create counter chains, or be tactically supported with action cards. This freedom in deckbuilding is a core appeal of Frontline Protocol - and long-term motivation for strategists.
