Q: With the recent restoration of Phyrexian Dreadnought when can we expect similar worded cards, such as Mox Diamond and Lotus Vale, to also be restored?

A: From Kelly Digges, Magic Editor:
This is a question we've received a lot ever since the return of Flash to its original functionality, and even more since the Tenth Edition update bulletin and the announcement that Phyrexian Dreadnought would be similarly restored. It seems at first glance that the printed wordings of Flash and Phyrexian Dreadnought represent the same case as the printed wordings of Mox Diamond, Lotus Vale, Scorched Ruins, and similar cards with comes-into-play drawbacks. Let's look at the printed wordings:
Hmmm. Those look the same to me—so similar that I asked Rules Manager Mark Gottlieb (who is way too busy keeping the rules from disintegrating to answer Ask Wizards questions) what the difference was. He didn't deign to answer—he speaks mostly in cryptic riddles these days—but he did email me the URL of the Weatherlight FAQ. Now we're getting somewhere. This historical document dates back to the set's release (though not, one supposes, in its online form). Maybe I can find a passing reference to it, or... ah, this should do:
Can I tap Lotus Vale for mana before I sacrifice the two lands?
No. You must deal with a card's coming-into-play cost before you may activate any of its abilities.
There you have it. Under pre-Sixth Edition rules, comes-into-play costs—much like phase costs such as echo—had to be paid before any of a permanent's abilities could be used. Lotus Vale and company could never be tapped for mana without paying the proper costs, and so their current Oracle wordings reflect only the changing rules, not changing functionality. By contrast, Phyrexian Dreadnought doesn't have any activated abilities, and Flash doesn't give you the chance to use them—the creature comes into play and leaves play (if you don't pay) all during the spell's resolution.
So don't expect to see errata for Mox Diamond, Lotus Vale, or Scorched Ruins. We might revisit them to get them even closer to intended functionality—you'll notice an interaction change with Ankh of Mishra, for instance—but all evidence indicates that they currently work the way they always did in the majority of cases.
If I flashed a Kiki-Jikki into play, I couldn't get a free swipe of it's ability? (It has haste already)
I assume that if I flashed a Sundering Titan into play, basic land types would die, but Kiki Jikki has limits on when you can tap it for it's activated ability?
I wasn't aware of limits on when one can use activated abilities outside of Declare Attackers/Blockers and Draw a Card durning Draw step.
Would someone care to elaborate on why Kiki-Jiki can't tap mid-flash?
