Lion Pride

2/1
Aftershock- whenever you play a creature you may sacrifice a plains, if you do you may return Lion Pride from your graveyard to play. Play this ability only if Lion Pride is in your graveyard.
This is less about the weenie aspect and more about the aftershock mechanic.
To me bringing things back from the grave is very satisifing, and provides some amount of assurence that you wont aloways be screwed in topdeck mode, so I decided to go about creating a mechanic that can do just that without being super broken but not completely stupid. I have been working on the ability for the other colors but the blue one seems to be the toughest. so far this is the blue instant:
Drouze



Instant
As an additional cost to play Drouze remove two cards other than Drouze in your graveyard from the game.
Counter target spell unless its controller pays
Threshold- Instead counter target spell.
Aftershock- Whenever you play an instant you may pay 3 life and sacrifice an island, if you do you may play this card from your graveyard as if it was in your hand without paying its mana cost. Play this ability only if Drouze is in your graveyard.
The drawback of sacrificing one of the native color producer of the spell is very critical, almost the same idea with pitch cards. I created some spells to have more of a drawback because of their possible abuse. At the casting level I dident want these to be very good thus making them more useful from the grave.
Questions, comments are greatly welcome.
