We give Elestrals a crack!

About Elestrals, from BoardGameGeek:

Elestrals is a brand new trading card game from the mind of Dan "aDrive" Clap. Dan and his team have been very involved with many different TCGs, like Pokemon. In a game of Elestrals, your Spirit cards are your most important resource: they are your health and fuel when playing cards and attacking your opponent! Knowing when to use your Spirits and when to save them is a key strategy. There are five types of Spirits. Most decks have a mix of different types, and the Elestrals and Runes that you Cast will often need specific Spirits or even combinations of them! To get started, each player has to have the following: A Spirit deck with exactly 20 Spirits in it. You can mix and match different Spirits or play as many of the same ones as you like! A Main deck with exactly 40 cards in it. This is where your Runes and Elestrals go; you can only have up to three copies of any single card, so you need some variety. And that's it! You can look through your own Spirit Deck any time you like and ask your opponent how many cards are left in their Spirit Deck. But you never* get to look through your opponent's decks, so you won't know exactly which Spirits they have left. Once your Main Deck is shuffled at the start of a game, you can't look through it unless a card tells you. -description from the publisher
