What is great about this card?

A good creature that provides decent card advantage especially when taken from the graveyard
- When you cast Champion of Wits, you will be able to draw two cards while discarding one. Already a decent value in terms of card advantage

What is great about this card?

Great card to have in mono-blue decks as it provides card draw as well as crowd control

- Once you flip this, you get a mana advantage as well as card advantage as you can dig through your deck again to look for specific cards off the top of your library

2. Shark Typhoon

What is great about this card?

A really powerful card when you get it on the board
- Every time you cast a non-creature spell, this enchantment triggers, giving you an X/X flying shark depending on the converted mana cost of the card you cast
- You can also use this for its Cycling cost, giving you access to a creature that can’t be countered

1. As Foretold

What is great about this card?

You get to cast a free spell each turn
