Spirit of Resistance and if your going to have haste Breath of Fury is a win con

carpecanum, oh I've never thought about Spirit of Resistance it seems like it could do some serious work. Also I've never even heard of Breath of Fury but that looks like a really great card that could catch a lot of people off guard, I'll most definitely consider finding a spot for it.

Hey, you've done well overall with card selection on a current $300 budget. The good parts of your deck are the robust Dragon base and the nice selection of Planeswalkers. What can be improved is the manabase, more ramp/color fixing for five colors and more repeatable draw/tutors.

The manabase is slow with the Thriving lands and the Vivid lands which all ETB tapped. My advice is keep five Thriving lands, cut the Vivid lands and one Thriving land? Replace them with lands that have interaction with basic lands because there's 21 basic lands here. The five budget Battle lands can help the manabase since they have interaction with lots of basic lands to ETB untapped and Farseek can search for one of them.

• Cinder Glade, Canopy Vista, Prairie Stream, Sunken Hollow, Smoldering Marsh

Cascading Cataracts is a helpful land to cast Ur-Dragon and Crop Rotation can tutor for it. Rotation can be sac a basic land to tutor for any land and put it onto the battlefield. The five Triomes especially Forest ones would be upgrades for Thriving lands: Indatha Triome ($5), Ketria Triome ($6) and Zagoth Triome ($7). The prices of Triomes are displayed wrong here, they're all much less price. Land ramp that can interact with Triomes can really help with color fixing. Skyshroud Claim, Nature's Lore, Wood Elves can search for a Forest Triome and Farseek can search for any Triome.

8 additional mana sources that are 3 CMC or lower is a low amount for a 4.7 avg CMC deck with only 36 lands. Consider a few more sources of ramp/color fixing? The most important cards to want to cast in the early game is ramp or a repeatable draw source.

• Faeburrow Elder: can tap for two mana (green and white). If you control other colored permanents it can tap for more mana up to five mana, one of each color.
• Arcane Signet ($4) and Fellwar Stone

Some more budget tutors could replace some of the lesser Dragons. More low CMC tutors can get the better Dragons/other cards while also lowering the mana curve.

• Eladamri's Call, Idyllic Tutor, Congregation at Dawn, Fierce Empath

Low CMC repeatable draw sources when Dragons ETB are very good especially ones that trigger when a Dragon token is created. Ascendancy and Kiora are here, but consider more? The more of these enchantments you have the better chance you have of getting one onto the battlefield before you start casting Dragons.

• Garruk's Uprising, Elemental Bond

Dragonlord Ojutai is a four drop Dragon thanks to the Ur-Dragon. It can potentially be repeatable Anticipate card advantage. The selection of what card you put into your hand is what makes it good on a budget.

Good luck with your deck.

multimedia thanks for the advice, I do agree my mana base is a bit slow so I am going to grab those five battle lands. I’ll also take the three triomes. And as for tutors, I generally try to stay away from them because I don’t really like them, I for the most part prefer the randomness of top decking. I feel pretty good on card draw as well, there isn’t a lot of removal in my playgroup and I can quite frequently get out my commander pretty quickly which is a pretty good card draw engine, plus I already have some other card draw through Dragon's Hoard, Zendikar Resurgent, Kiora, Behemoth Beckoner, and some of the sarkhans to name a few. But thank you for all the suggestions
