Mono white test utilizing Odric, Lunarch Marshal.Transformative sideboard to become a mini G/W Humans.
Gisela, Blade of the Goldnight is my proxy for Gisela, the Broken Blade.
At first glance this deck doesn't do much but with some setup, it can be deadly.
The deck basically makes little threats with various keywords until Odric, Lunarch Marshal comes out and gives everyone everything you currently have on the field.
For example, lets say you have
Aven Sunstriker
and
Kytheon, Hero of Akros
on the field. By themselves these cards aren't scary but you drop Odric, Lunarch Marshal on the field and all three of your creatures now have Flying and Double Strike with the possibly of indestructible if needed. The deck can also give first strike, vigilance and indestructible depending on your board presence.
The only problems with this strategy is the fact that Odric's effect only takes place during combat so before and after combat creatures can be removed to prevent everyone from receiving the buff they could have given. Secondly, your opponent knows your gimmick after game one and will be prepared. Odric probably will never successfully hit the field after that, hence the transformative side board. If you lose game 1, win game 2, you have ability to choose which version of the deck you would like to play game 3. Basically leaving them less room to side effectively against you, unless their side works against both playstyles.
In any case, I hope you like the deck and I look forward to your feedback!
