@Cepitore - Thanks for noticing, I have been adding creatures which has a lot of value but doesn't contribute with the deck/commander. I have revised the deck now as best as I can.

@Dis4Dinosaur - Tower Defense should suffice. I don't have other cards to replace with Bar the Door in the meantime. Thanks for the suggestion though.

@SyrJet - I won't put any walls in this deck, it's been hard for me to remove the defender status of walls when it's time to all out attack, unlike high toughness creatures. Thanks for the suggestion though.

@Bezter - My problem with Builder's Blessing is that when my creatures doesn't have vigilance and attacks, the effect wouldn't be fully used. I have already bought Tree of Perdition and Karn, Silver Golem is an interesting choice, but I already have a lot of CMC. Thanks for the suggestion.

@i24 - it was just because i had that planeswalker, and i might as well use it. But now i have removed it, since as much as it has a lot of value, it wouldn't fit really into the deck.

@Chaseace3 - Thanks! I found some ideas in your deck, like Behind the Scenes and Trostani, Selesnya's Voice .. Although, I ultimately didn't include trostani, since I have a bit of lifelink, and that would overkill. Also it has specific mana color to cast.

@Bluerunt - It's the same with Trostani, Selesnya's Voice , but a lot more to cast and would increase my mana curve.
