how come none of these work for me? my browser says it can’t display the webpage, etc.

I really don’t like shriekmaw to fill the two drop spot on the curve (he’s fine if there are enough other spells to play on turn two). On the play, or if the opponent doesn’t play a two drop, rampant growth is the only spell until turn three. If your willing to play land go, land go, on the first two turns you should just play five color control.
