Bigger Than Big

This is a problem:

I'm supposed to have giant dragons on the battlefield and instead I have...Fledgling Dragon. One.

I played a few games with Gigantor as it was in order to get a sense of what it needed. The basic problem: I couldn't stick a big enough threat on the board.

This might be due to some variance: mana issues were abundant in the games that day. That should be unusual, since I have eight ways to boost my mana production.

But mana production doesn't matter if I follow it up with a 2/2 flier as a threat. That's just terrible.

I know going in that most of the decks I'm going to be playing are rough, but I rarely have an idea of how rough. This one is needs a whole lot of sanding down.

I've got some ideas for changes and writing this reminds me that Gigantor is a pretty good opportunity for cards like Radiant Flames and Painful Truths to find a home. Cheap solutions to give me time to put threats on the board should be right in the arena of what Gigantor wants to do.

 In addition, a commenter from the Reddit thread where I posted the deck reminded me that Thunderbreak Regent exists-for some reason I forget about that card-as well as Scourge of Valkas, which is very tempting but at RRR in the mana cost is probably not going to fly.
