Couple of others that look pretty good to me:
Silent-Blade Oni

Creature - Demon Ninja
Ninjutsu



Whenever Silent-Blade Oni deals combat damage to a player, look at that player's hand. You may cast a nonland card in it without paying that card's mana cost.
6/5
Another ninja to join Ink-Eyes in my stack! This one looks even better as it will almost always have a target and can lead to some devastating plays. Sucks without the ACC rule though.
Dragonlair Spider

Creature - Spider
Reach
Whenever an opponent casts a spell, put a 1/1 green Insect creature token onto the battlefield.
5/6
Less great, but can still put out a sizeable army of chumps if left unmolested.
Vela the Night-Clad

Legendary Creature - Human Wizard
Intimidate
Other creatures you control have intimidate.
Whenever Vela the Night-Clad or another creature you control leaves the battlefield, each opponent loses 1 life.
4/4
Definitely the least powerful of the three, but still gives your other dudes evasion and can punish someone for wrathing.
