Icefang raptor... look really cool and awesome, but in PvP there won't be many S units in T2. For the few S units in T2 frost splashes have better options like lost reaver, razor shards, scythe fiends, or just MA and frostmages from T1.
The shieldbuilding thing looks lame, but would the shield stack with other shields, like the shield building spell for instance. That would make it way more powerful, but also more expansive
@Nick I am not sure if Loptous (the op of this thread) is cool with people just posting stuff. It might be better to send Loptous a pm with the card you want and he will then put it here.
