In my opinion it would be better to make physical cards or use a maker specifically designed for TCGs. RPG Maker is best used for RPGs after all. Maybe something like Unity is more your thing if you want to go digital. I've seen TCG Kits for Unity out there.
While technically true, it is still very possible to do it in MV. However, I don't see that happening without some serious determination and knowledge of scripting/plugins since you would have to basically overhaul the entire UI and systems for the game.
As for a TCG, you can use pictures as the cards easily enough, and design the "board" or "field" they go on by using the tilesets like anything else. For the battle you'd have to follow a lot of RNG aspects and use events to simulate several possible ways to do things. It's quite tedious to do something like this in RPG Maker.
If you want a nifty summon feature, simply make an item "named card" and tie it to a common event when used in battle. So for instance:
Player uses card named "Rex".
Common event then makes player say "I call Rex to the field!"
Change player spriteset to that of "Rex"
Change player class to that of "Rex"
Now you are the creature in battle and have access to all of it's abilities and such.
Enemies turn. Enemy uses card named "Bronto"
Common event makes enemy say "Bronto, I'm countin on you!"
Change enemy to "Bronto" Sprite
Give "Bronto" skillset to enemy
Now both sides have a creature out and can battle till one is defeated. After end of the battle change player sprite and class back to original.
Something like this would work pretty well if you call the common event at the start of a battle to force the player to choose a card in their hand (determined by an RNG factor and what cards they have in their "inventory/deck") and same for the enemy. But yeah, hope that can generate some ideas for you lol. I'm an eventer so I can see how to do some things like that effectively enough.
