Question about prince renathal card

Well i know what the cards effects are because basicly everyone and their mom is using this card.

But i got a more specific question.

Since it increases your deck size, what cards does it add to your deck? Are they copies of your own deck or random cards. And if they are copies of your own deck, how is it decided wich cards get an extra copy? Is it the first 10 cards of your deck that get copied or are they entirely random copies

Im kinda trying to figure out of its worth adding to my deck or wether it would clutter things up

Decks are limited to 30 cards while building them.

Putting Renathal into the deck increases this limit to 40 cards.

So there are not 10 cards added to your deck but you yourself can add 10 more cards into your deck while building it.

that makes sense, i thought it increased your deck at the start of the match like some other cards.

So you can actually select those extra cards yourself? that does make it worth trying out

Be careful though: more cards means more options but that can also make it harder to draw certain cards you need in a situation. It’s a double edged sword.

Thats okay i use the educated elekk to dump alot of spells into my deck anyway. So it can get messy sometimes xD but now i know this its worth making a copy of my deck and try adding some new cards
