Okay, well, first off, as Klasp was targetted by mugic, you should probably have used his ability to sacrifice and deal 10 damage to one of the opponent's creatures.
Lore is DoP

But make sure there are no loyal creatures in your deck. If, for example, an underworlder is loyal, he can only be paired with other underworlders. For cards from Silent sands, Zenith of the hive or dawn of perim, it says "this card may not enter mixed armies" instead of loyal.
Lore had no fire, that's true, but he doesn't need it. Your mugic users shouldn't really fight anyway. The basic principle of deck building in chaotic is to have your main warriors fight and your muges support.
Underworld mugic is most often offensive, but don't rely on that entirely. 2 offensive one defensive should work. So something like..
Song of Fury
Canon of Casualty
Emberflourish
Or exchange Fury for a Discord, always nice to remove battlegear. Lore has a thirty damage burn, so you will have a lot of good mugic/ability support. Also, Toxis has two counters so he is a good mugic user. He has recklessness 5, so give him a viledriver and he'll be like a second magmon. He can cast Canon and Discord, while lore can cast ember flourish if needs be, or deal damage with his counters.
