The Basic Water Energy card powers Water-type moves
The card is not splashy, but it reminds me quite a bit of another card previewed in a Commander deck that didn't seem all that splashy at first - Scavenging Ooze
This is because Leafeon ex is the one who will need to spend more time in the Active Spot , building up your ambitions through Forest Breath
Further Upgrades The first cards I'd pick up to further juice up the deck would be untapped mana-fixing lands: Watery Grave, Shipwreck Marsh, Underground River, Morphic Pool, Darkslick Shores, Polluted Delta, Sunken Ruins, Undercity Sewers, Urborg, Tomb of Yawgmoth and then maybe a couple more Island / Swamp fetches
One extra turn buys you plenty of advantages
