RU Dragons v2.0 (Casual)

Massive overhaul of an older R/U Dragon/Illusion Tribal Deck. Now going pure Dragon Tribal.

The concept is fairly straightforward. Pump out Dragons to fly/overrun damage opponents with some built in burn for extra damage from Dragon Tempest and Molten Echoes. Because of Tempest most of the sorceries/instants offer great utility as creature production and damage/control for opposing creatures. Hidden Strings is a sneaky blue aggro/ramp card that can be used to slow down opponents if you sub in more hypersonic dragons.

The sideboard is still a work in progress and currently just contains lots of other cards I wanted to make the cut. Will need to play the deck out several times to see which strategy is most effective and efficient.

Underrated cards in the deck and why:
Hidden Strings is so versatile, and with flying damage you get the free cast fairly consistently. It accelerates your mana or works as pseudo-vigilance.
Cryptoplasm can quickly give you two of your bigger dragons later on, and can help defend against bigger opponent's creatures by simply copying them. If I chose the more card/drawy protection route and ran Loch and Thunderbreaks he would be even more devastating.
Sundial of the Infinite totally breaks Molten Echoes, Twinflame, and Voidwalk by preventing the end of turn delay triggers, and making the effects and permanents unending. Must be used carefully.
Mirrorwing Dragon is great anti-hate/removal as it will turn most anything charged against it onto your opponents en-masse. Additionally you can copy it, untap it, or voidwalk it to ripple onto all of your other creatures an cause a massive void-bounce/flicker to do huge simultaneous ETB damage with Tempest.
Role Reversal is also a really funny control and manipulation card. You freely steal creatures with it by using Voidwalk to bounce any you give to an opponent back onto the battlefield under your own control.
