good card should be a bit less mana to play

If only he was a warrior as well

He should be, look at that beefy club

I think at 4/4 to take it out of bolt range and change it's cost to {4}{R}, this would be solid, and yes give him the warrior creature type as well!

@NoobOfLore: Red can get a 4/4 with haste and flying for , in form of Volcanic Dragon, even at the time of Urza's Saga: the dragon is from Mirage...

Average card, not good, not bad, "normal". In a giant deck this can be a choise, even if I'd like Thundercloud Shaman in the same slot, maybe... However, I don't run a giant deck, so I don't know actually...

Bonebreaker Giant says NoobOfLore is full of crap.

Power him up and make him easier to cast?
I don't think so.

Remember Hill Giant? This guy only costs one more than that.

Red just doesn't get 4/4 for 5 without downsides, and a 4/4 with haste would push it at least to 6 mana, if not another .

Edit:
Oh look guys, new cards were printed. I guess statements made about cards that are currently printed DON'T hold true eternally. Thanks for pointing that out.

Volcanic dragon costs 1 more, and is actually pretty good.
Bonebreaker giant is a 4/4 for 5, but it doesn't have haste now, does it?

Draft filler nothing more. for 4/4 haste would be fine. How often is Stampeding Rhino played? Bonebreaker Giant is so bad in constructed that its never played, only use is a draft filler. Giving it haste would be progress, stronger creatures for a stronger metagame.

Lol, this card looks so weird.

According to the flavor text, this giant enables faster than light signaling which should permit transmission of information through time if abused correctly. I'm sure there's a way to use that to my advantage in a deck...
