How Oracle and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Oracle and Io win 48.83% of ranked matches when playing on the same team, over 1,716 matches.
Pairing these two heroes often creates a very defensive and passive laning stage. Both Oracle and Io want to sustain a core, but they lack the combined lockdown or damage to threaten kills or effectively trade with aggressive opponents. This can lead to a slow start for your entire team. While their ability to stack saves on a single carry is powerful—making someone with False Promise and Io's tethered buffs very hard to kill—it's a resource-intensive strategy. The rest of your team is often left without stuns or initiation, making it difficult to control teamfights or create your own opportunities on the map. The game plan becomes too predictable.
How this pairing performs across skill brackets — the duo's team win rate in recent ranked matches, split by average match rank. Ranks with too few recent matches are omitted. These rows use the last 30 days of quality-filtered ranked matches, all patches in that span combined — a wider window than the patch-scoped count above, so the per-rank match totals can exceed it.
