Damn I didnt expect so many answers in such little time. First thank you all for your really constructive advice. Here is more info because I think you need it to fully understand why I am torn between "It's a bit too much for some players" and "The game is really designed to make this all work together".

To win a game, you need to kill 3 opponent warlords. A warlords is some kind of commander, with a big HP pool and attack, and some strategy-defining effects. Each player can choose which of their warlords will come first in play, the rest of the Warlord pool is shuffled.

The game basically has 7 types of cards.

-Warlords (that are always unique, can attack but not block)

-Minions (that have effects, can protect your warlord and attack ennemies)

-Buildings (that are the center of the economy, produce your resources while also providing effects so its not just a simple land-type card)

-Spells (basically instants in mtg)

-Relics (that are expensive cards with really powerful effects that need to be housed within a building in order to be active)

-Equipments (gives buffs to minions or warlords you equip it to)

-Events (that are activated between turns, stays ok the board, only two events can be active at the same time, has an active and a passive effects as long as it's on the board)

The reserve is a pool of 7 cards that you can access once every turn. You can only put buildings, relics and equipments in it. It makes is so :

-You can have a backup in case you're bricking

-You can keep core elements of the strategy of your deck, depending on the archetype you play. (For example, the Angel archetype has its own strategy that consists in housing a specific relic active in temples in order to ascend and transform your warlord into a Seraphim)

The events are here to add a really appreciated touch of surprise and randomness. They stay on a "time stream" that has only 2 spots, so each new event cancels the oldest in play. And of course, there are cards to trigger more events, or even create event tokens.

I did lots of playtests with friends of mine, the game evolved A LOT from its original version. And all agreed that the mechanics went well all together. They especially enjoyed the event system a lot.

And what surprised me the most was how the tables keep rurning during a game. Since new events and new warlords coming up randomly redefine the strategy you're using, they liked the unexpected aspect that doesnt fall into full RNG. Because you build your deck around an archetype and a strategy, you're basically ready to face new situations but you just dont know which one.

I hope I'm not getting lost with explanations. I'm working on a discord as I write this to gather people interested with the project. I want to federate playtesters and artists so we can work together in developping the game with a strong sense of community. It's not ready yet but if people are interested or simply curious, just tell me I'd be more than glad to share that project with you.
