MTG Salvation

I'm building a EDH mono-white blink and I am looking for cards that have an effect when another card enters the battlefield that does something other than give life.

Any help is appreciated.

I am thinking of making a janky deck and the card Gravity Sphere seems perfect for the job I need done, I'm just not entirely sure how it works in the long run. I looked at the rulings for it and it says that creatures on the battlefield and entering the battlefield lose flying, and my uncertainty with how this works comes in when you involve the latest set, Ikora. The deck is based around the idea that you use Luminous Broodmoth to make all creatures you control immortal and abuse ETB and other effects. Would Gravity Sphere prevent these fliers or do the counters overrule it?


Also, can anyone provide examples of cards that would work the same or better than Gravity Sphere for a task like this?

Making a janky lands deck and need the ability to force lands onto people or swap lands in mono-green. Any help is appreciated.

Sorry, already found what I needed. Nevermind.

I'm building a deck around enchantment creatures, and when I saw Archon of Sun's Grace I remembered something of extreme stupidity. I am requiring help to find a single card at most, and the card required is an enchantment, artifact, or creature that makes it so all new creatures now also count as enchantments. This is so that I can trigger Archon of Sun's Grace ability infinite times until someone has removal, essentially stalling the game until removal is found or until my opponents concede. You may think I am the ******** for doing this, but since it isn't a may ability and I feel autistic at the moment, I hope you guys can help me.

So I was reading the card, Captain Lannery Storm and wondered; if I were to equip something like Blade of Selves would I then get all of the attacking triggers from the tokens or would the legends rule occur first causing for no attacking triggers to happen. I'm not asking if each token would deal damage, I know that the legends rule at least would make me kill them before that happens but I just want to know if the myriad tokens would cause the attacking trigger to still happen.

So, I'm not the brightest and often think of stupid stuff. I can't find anything on this, so I am just asking direct (Please note I suck at reading and searching). So, the question is on the Tap for any color as seen on cards such as Manalith would I not be able to tap for something like purple? If anyone wonders why I ask this crackhead question it's because of the Sunburst ability because if I can make those other colors then I will be able to pull some stupid stuff.

If I were to cast the spell Mana Drain with, for example, Melek, Izzet Paragon's ability causing a copy of the spell can I say that the Mana Drain targets the same spell allowing for two times the mana gained from the CMC related ability, or does that not work?
