Taniwha
Trample Phasing (This phases in or out before you untap during each of your untap steps. While it's phased out, it's treated as though it doesn't exist.) At the beginning of your upkeep, all lands you control phase out. (They phase in before you untap during your next untap step.)
How Taniwha decks play in EDH
Taniwha is a mono-blue commander costing 3UU, and its legendary creature - serpent line shapes the whole deck around it. Its ability is narrow enough that the deck is usually built to protect it and repeat the effect, rather than to go wide. The cards below are the ones Taniwha decks actually play most often, grouped by the job they do.

Start with TaniwhaTaniwha deck questions
What colours can I use in a Taniwha deck?
Taniwha has a mono-blue colour identity, so every card in the deck must be blue or colourless. That includes mana symbols in rules text, not just casting cost.
What are the best cards for Taniwha?
The cards played most often in Taniwha decks include Omnath, Locus of the Void, Gandalf, Shadow's Foe, Elven Raft-Steerer. The full list of staples above is grouped by the job each card does, so you can see the deck's skeleton rather than just a pile of names.
How much does a Taniwha deck cost?
The 20 most-played cards shown above come to roughly $95.85 at current market prices. A complete 100-card build costs more, and Grimoire can generate a budget version instead if you set a price ceiling.
Can I build a Taniwha deck from cards I already own?
Yes. Import your collection into Grimoire and choose "my cards" when you build. The generator will only use cards you actually own, and the Missing Cards page shows what you would need to buy to finish any list.
