{Old version with unconditional tapped ETB}

thaneofglamis - I like the use of Foremost here - mana fixing is usually important in the earliest turns so if you set things up right you can still get your mana fixing and stay on curve for creature based decks while keeping your creatures to an acceptable minimum for control-based ones. To be honest though I think this would've been a more interesting card if it ETB untapped, and produced without foremost and <color combination> with it. That would lead to some interesting deck building decisions in both Standard and more eternal formats as well as make them interesting options for Voltron EDH decks, whereas as is they're kind of just Vivid lands with the parts just shifted around a bit. Flavor is fairly simple but works just fine for conveying its place in an African set.

kefke - This is a pretty cool card for conveying both the flavor and encouraging morph as a strategy. Fertile Ground suggests you've costed this fairly enough as well, and I like that you can have multiple creatures as long as you keep one morphed face down. It feels like you integrated the source material very well and you made me think a bit about how it would be played.

Small wording mistake: You need "Enchant land" at the top of the text and Overgrowth suggests you should be saying "controller adds" (for additive mana production) instead of "produces" which is usually reserved for replacing or multiplying mana production. Otherwise, nice work.

Boogymanjunior - Hm. I like the fastland riff, but I can't help but feel the idea of choosing a color and being forced to keep track of it creates an unnecessary memory issue for what should otherwise be a simple card. I'd remove that and either replace it with " Add ..." (Which would fit with the lore nicely, becoming more generic land after the most important time). I feel like this design is also overall just a little less graceful than the fastlands in general, where I really liked the "two or less" restriction because it gave you some leeway in when you drew or played them - this sort of pushes it to the extreme of where you absolutely want it to be in your starting hand or it just sucks. I'd much rather have had something like "ETB tapped unless one or less" combined with something like say, Reflecting Pool, than what you've currently made. A functional card, but I feel like it needs adjustment.

viriss - I'm not seeing what exactly makes the Ibis a solitary bird from a quick search - a short explanation would've gone a long way here. It's a cute voltron-esque effect and I see how it's meant to effectively double your mana while forcing you to stay all-in on your bogle/voltron creature/etc...though I admit it also kind of feels like the effects are just sort of thrown together into a convenient package. The end result promotes an interesting strategy but I get the nagging feeling that something's missing - most likely a flavor justification to tie it all together, or the greater context of a set failing that.

Thinking about it harder I think the reason this card falls short is because it demonstrates a problem with "Chinese Menu Design" Mark Rosewater has talked about in the past. The abilities don't really have a relation to each other and aside from flying the card is primarily Green - to the point if you took off Blue and Flying and made this a monogreen Aura, I think it would've actually worked better. The card is perfectly functional and could go into a set as-is, but I think if I was Design I would be pushing very hard for this to be monogreen with trample.

ameisenmeister - A super restrictive but extremely nasty Glorybringer if it gets online...hm. I think, given the fact it basically spits out a creature-focused Bolt each turn, it might actually be wiser to make this Gruul instead of Selesnya, dropping the Lifelink because the effect is pretty powerful by itself. Getting a land-matters boost also tends to be in the realm of Gruul more than any other color combination though I guess you could make an argument for comparisons to Knight of the Reliquary. This probably can't coexist in a Standard environment with something like Utopia Sprawl or Search for Tomorrow but other than that I think it's alright - just maybe the wrong color combination.

Your render is carefully chosen and helps nail the card's flavor well.

somerandomperson - That's a lot of hoops to jump through. Not only do you have to wait until the beginning of your next upkeep, you have to sacrifice all your lands for what feels like an incredibly boring payoff. I think this is not a good design for new players in general because they are generally hesitant to do something like sacrifice all their lands - in general, an effect like this is not printed often because it means you end up not playing Magic after you use it.

So if this isn't for new players, could a veteran player appreciate it? I think the answer would've been maybe if you could combine it with Armageddon or Fall of the Thran type effects, but because you've explicitly specified five basics unlike most Coalition Victory cards and an upkeep timing restriction you can't even really do that much.

I think both of those points lead to what I really don't like about this card: it's basically just "5 mana = I win" and tries to hide that behind some very frustrating restrictions. I understand you were trying to make it feel clever but there are a lot of better ways to reward land-based payoffs that aren't nearly as restrictive to the player and designer and feel much more creative overall - see Rampaging Baloths, Zacama, Primal Calamity, Golos, Tireless Pilgrim, etc... There's also pretty much no African flavor to this that I can immediately see - one of those times where one line of explanation goes a long way.

You have the right idea - players do like working for their win conditions, but players also like it when both the journey and the end have exciting results. I don't want to come off as overly harsh, but the journey and end of this card both need a lot of work to get there.
