With the Glistening Edges

Research begins: 

If nothing else, I need to let go of what this deck was and look at what people are doing with it now. So much has changed in the Magic landscape since the original Astral Slide decks were a thing that it's only sensible to see how it's advanced.

And they are doing something completely different. 

Why try to sneak a big creature into play when you can abuse enter the battlefield triggers? 

So here's what I ended up building out of the cards I had available. 

2 Tilling Treefolk
2 Titanic Bulvox
4 Flourishing Fox
2 Eternal Witness
4 Knight of Autumn
1 Charming Prince
3 Thragtusk
2 Splendor Mare
2 Titanoth Rex
1 Greater Sandwurm
1 Valiant Rescuer

1 Astral Slide
4 Astral Drift

2 Secluded Steppe
3 Tranquil Thicket
1 Grasslands
4 Plains
6 Forest
4 Scattered Groves
4 Overgrown Farmland

4 Edge of Autumn
2 Wrath of God
1 Akroma's Vengeance

And whoa. What an improvement! The deck actually did things!

I'm still having a little trouble; if I draw the payoff cards but no cycling then obviously that's an issue. But at least I'm getting to play the game in a way that executes the plan.
