I hate everything, especially myself
Some thoughts about the card choices
Siege Rhino- I think this is a decent magic card, but I'd like to do some testing in Vintage before deciding.
Bring to Light- On occasion, you will be tempted to use this for something that isn't a Siege Rhino. This temptation is to be avoided at all costs.
Clever Impersonator- Bonus Rhino.
Emeria Shepherd- Imagine getting another Rhino EVERY TURN, FOR FREE. Yeah.
Greenwarden of Murasa- This will help your Rhinos not only survive wraths, but also return with another lightning helix to the dome. Don't even bother trying with less than four.
Jace, Vryn's Prodigy
- This seems weird, but you have to recognize that you can use the -3 to recast a Reclaim, See the Unwritten or Kolaghan's Command to get more Rhinos. You can also, in theory, discard a Rhino to maximize the value of Kolaghan's Command.
Kolaghan's Command- Don't use these early on! Save them for when you have dead Siege Rhinos to revive, or you're wasting valuable Rhino slots.
Mortuary Mire- See Reclaim. Also taps for mana.
Reclaim- Best used to recover a dead Siege Rhino.
See the Unwritten- Because paying 6 mana for 2 Rhinos is just value.
Ulamog, the Ceaseless Hunger- They'll be so blinded by rhinos that they'll never see it coming.
Sideboard:
Aligned Hedron Network- I'm sorry, my Rhinos can't get through your blockers? I'm afraid that's just a lie.
Atarka's Command
- Use it to play more lands to get earlier Rhinos, and to shut off the lifegain from THEIR Rhinos.
Mantis Rider- [22:56:01] GreaterGerardon Moving the riders to the side is bold.[22:56:06] GreaterGerardon but that means more rhinos.
Clever Impersonator- Sometimes, you need to side these in to beat the insidious 43-rhino deck with your all-powerful side tech into the 44-rhino deck.
