Hi, I'm a noob on magic and I want to know if you can use "Deflecting Palm" into a Eidolon of the Great Revel... I mean If I need to deal 2 damage to my opponent (for example), can I use Deflecting palm, Eidolon make me 2 dmg, I don't take that and redirect?... And, if I take that 2 dmg, but then I play a Lighning bolt or lava spike or something like that, Eidolon makes me 2 dmg, can i redirect that and deal 5 dmg with the eidolons and the spell?... Thanks a lot :)
However, you can choose Eidolon as the source when Deflecting Palm resolves, and the damage it would deal to you for casting your next cheap spell this turn will be dealt to your opponent instead, so you can bolt for 5 as you said.
