MTG deck build ideas?

Since you are going to 'cheat' on the mana cost, I do not see why we can make a mana base more friendly. Having 5 of each basic land makes your land draws very inconsistent.

This is what I would do:

First get the dragons:

4x Worldy Tutor

2x Time of Need

These 6 spells will help you get the dragon you need for the situation.

The dragons:

1x Dromar

2x Numot

1x Oros

2x Darigaaz

2x Crosis

1x Intet

1x clockwork dragon

Only 1 intet and 1 oros, since they are the more situational of the dragons. An early numot is overkill. There is only 1 dromar because 60% of the time Dromar will bounce itself (which is kinda cool with dragon arch). Clockwork dragon is there because it can be tinkered in turn 3!!!

The mana base:

14x Forests

4x -green artifact land-

4x seat of the sinod

2x island

the mana fix:

4x sakura tribe elder

they can block early, and also search for lands.

You want some blue mana for the early defense.

4x dragon arch

4x aether spellbomb (this will be your defense/draw cards).

3x aether burst

To look for the dragon's arch:

2x tinker

There are few spots open still so you tweak the idea.

Good Luck

WOW....you are really hopin here. This won't be a "winning" deck, but it sure will tick off people

Dragonspeaker Shaman would be one card I would add. It lowers cost by either 1 or 2.

I don't know if I don't look at the RAV uncommons dual lands. Yes, you have to pull a land back, but, you gain a mana over all. I'd think about it.

Some Land fetching wouldn't be out of the question

Kodama's Reach is my fav

Sakura Tribe Elders is good

Rampant Growth

Explosive Vegetation

You need to get your land out quick and fast.

that's my take.

Try this -

Elvish Champion. Green, tap, You may put a creature card from your hand into play.

Also, Captain Sisay: Tap, Search your library for a legendary card, reveal that card, and put it into your hand. Then shuffle your library.

So for a Green and two tapped creatures, you can search for the dragon you need and put it into play at the end of your opponent's turn.

Reya Dawnbringer is also good, as she allows you to take a creature from your graveyard to play every turn.

I would definitely look past basic lands. Very, very hard to get the right colors without dual lands, pain lands, etc. Using spells like Harrow, etc (anything that lets you search for land) is good. Thins out your deck and allows you to get what you need.

Since you are building a DRAGON deck you will need Dragonspeaker Shaman and the artifact Cloudkey. Also Wild Pair is a great enchantment to use in this deck.

I'm pretty sure merigold meant Elvish Piper, not Elvish Champion, I would use Reya Dawnbringer as someone else mentioned, in combination with cards like One with Nothing, or cards to mill yourself to put dragons into your graveyard. Balthor the Defiled would also be nice in bringing your dragons back

You have mostly ones and twos of cards and this deck is not standard if that's what you're going for.
