Dare you to play that Land !

I know this is in progress but you published it anway and one of the tags says "need help", so here we go:

You either need more creatures or to get rid of the ones you have currently. Thing is, if you have that few creatures with such low toughness, you are going to lose them very quickly. Virtually every deck runs creature removal, so if you play a toughness 2 guy without evasion every fifth or so turn, they won't live long.

Tamanoa is problematic anyway because she needs all three colours. And you'll never going to get her into play in time with a mana base like this. Moreover, as of now, Tamanoa provides the only form of lifegain so far and without continous lifegain, Searing Meditation is useless. Since these are the only white cards so far, I would cut both Tamanoa and Searing Meditation. If you plan to hang on both of them, however, I recommend Recumbering Bliss to neutralize opponent's creatures, get some lfe back and in turn to trigger Searing Mediation. You might also want to play with 4 Searing Meditation in that case. If the Meditation deals damage to an opponent and Tamanoa is in play, you will gain life and thus can activate Meditation again. That's a damage and life loop as long as you have the mana to activate the Meditation. But beware, if you focus on this, the theme of the deck might shift away from the Ankhs.

Tectonic Instability is totally useless (here). First, it effects yourself as well. Secondly, your opponent can always use his lands in respones to the trigger and get all his mana anyway. All that Tectonic Instability does is forcing your opponent to tap out. But he will do that most likely anyway in order to mount his own offensive and to beat you down.

I don't know what format you are aiming for, but Black Vise is better than Ebony Owl Netsuke in most situations.

Cards you might consider adding:
* Avalanche Riders: They kill a land and thus give your opponent a reason to play more. But they also provide a blocker or attacker, whatever you currently need. Moreover, if you insist on keeping Tamanoa, adding more creatures increases the chance of survival for Tamanoa. This is of course true for adding any creatur, so I won't mention it again.
* Stuffy Doll: You'll be in the defensive most of the time. Stuffy Doll can't handle flyers and Tramplers, but apart from that a Stuffy Doll is a nice roadblock that helps you either winning the damage race or stopping all groundbased attacks alltogether.
* Veteran Explorer: This is almost a must in this deck! He blocks once and then he fixes your coloured mana problems, at the same time it works towards your goal. And all of that for a single green mana!
* Tunnel Ignus: Might be worth adding if you keep the Rites of Flourishing and also add the Veteran Explorers.
